steve: whenever i come here i think about him. charlie: was it the thing that sticks deepest in usa sense of desk was a sense of he lived and give it all you got? steve: he instilled that in every waking moment when i was around him. he was the busiest man that i knew, and his work ethic was insane. he is always drilling that into his kids and into me. charlie: but you have that, the same kind of work ethic. steve: i feel like he taught me -- in a way he instilled this idea that you have to do it on your own, i cannot just handing steve chris if i hand things to

you you will not understand how to survive. if i was like this is my business, benihana, i want you to follow in the footsteps, then i might not learn the survival skills and business to possibly run a company like that. instead, he said figure out what you need to do with your lives. when i decided it was going to be far different than what he expected, then he was like, ok, this is not what i intended when i said step out on your own. then i had to prove to myself and to him that i could actually make it on my own. at the tail end of his life i was able to show him that i got to a place were he did not have to worry about me. charlie: was music part of his life? steve: not really. he was a basis in high school.

i think he retired that because he did not see a career. when i picked it up, when i picked up the guitar and the base and started being in bands, i thought he would share an affinity with me. at the time he said to go and have fun with your toys and you will eventually grow up. i did not realize that this was the career path i wanted to choose. knowing that when you are in this band, you not making that much money. when you are starting a label, you're not making much money. he saw a short lifespan, as far as where my career path was going. just like any traditional japanese parent, he said you need to wake up and get a real job, a stable job and you will not like it, but you will have to do that. charlie: you said once that if you were not a dj you would be dreaming of life as a dj.

what is the life of a dj? steve: i guess the life i am living right now. charlie: in music? steve: exactly, making music and playing your music. it is the same thing i was doing when i was in a band. charlie: is it the performance aspect that is the most appealing to you? steve: you make the music so that you can connect with people when you play it out. when you play to a global community, you play all over the world and you get to cb impact it has two people in spain to el salvador, to japan, to all over europe, to america, it is incredible having this global connection. ♪

♪ charlie: do you consider yourself an artists, a musician, a dj, what is it? steve: i would say it is all of the above. charlie: it is performer, creative? steve: dj kind of wraps up at all. charlie: what is the deal about cakes at the audience? steve: there was a point in time where i was not doing any sort

of activities on stage. when i had the opportunity at coachella in 2009 to have a stage show, i thought about what i would be bringing to the stage. i thought at this song, i will stage dive. at this song i will bring out rafts in the crowd. i was thinking of new ideas to entertain the audience. some of them stuck and summer popular. the caking was something i introduced in 2011. every artist wants to bring something to the show, where it is like hey that is a steve aoki thing and i want to get caked in the face. charlie: it is a defining act? steve: it makes it unique. when you go to the show you are experiencing it. charlie: tell me how you think you changed electronic dance

music? how did you make it become more of something? steve: i was definitely a part of a group of people that brought a level of entertainment, if you will, to the show. i brought a level of entertainment that might not have been there before. i just added more color. as far as the production side of things, which is why people even come to the show in the first place, you have to have the music to drop people there. my goal is always to work outside of my status quo world. i prefer to work with hip-hop artist. i am working with country artists and thinkers who have not worked in the space. i am trying to find new ways to reinvent the sound and not be so pigeonholed. the sound is changing. charlie: how is it changing question mark steve: --

changing? steve: chain smokers and calvin harris is always being number one. it brings us more of a form to think outside of the box and not think if this will affect only on the dance floor. charlie: where do you think you are in that? you know her calvin harris is, where are you? steve: if i think, i need to write a number one hit so that i can survive, i have always survived without even having hits. that is where i feel lucky. my music survives in that world. of course, we can all dream to have songs that permeate culture and are listened to by millions of people. that is essentially the goal. charlie: tell me about your social media. steve: for me it is a big deal.

you get instant feedback. it is not always good, but i love the feedback. the feedback is a big part of the process. charlie: where do you see the evolution of all of this? are you just in the moment and that is it? steve: everyone thinks about the five-year plan. charlie: it is not so much a plan, but how it has its own momentum and you know it is going somewhere, or headed somewhere. steve: that is the hardest thing to answer. that question is always asked. where is our music going? it is always fluctuating. charlie: but it has never been bigger, never been stronger, never been more listen to. it's moment is now? steve: there are artists have -- you have reached the top of the charts. you always have that outlet and it is incredible that we have that.

charlie: suppose somebody is watching the show right now and they are saying to themselves, what is electronic dance music? is that simply what they say, electronic, dance and it is music? steve: that is why it is a great term for it even though it is five or six years old. the words are very much what it is. basically it is about these producers who produce electronic dance music, and you can merge with different john russ. genres.rent charlie: where you want to be next year, if you come back and do another interview. steve: i would love to come back in a year. i have my previous projects. i have a third one coming and working on that outcome. -- on that album.

charlie: we turn now to a

remarkable conversation between two performers. michael phelps and mike krzyzewski are two of the most highly decorated competitors in sports history. phelps achievements as an olympian are unprecedented. he finished a career that spanned five olympics and 23 gold medals. no one has one more college basketball games than mike rusedski. k.games than coach he led team usa in the real olympics where he became the first national team head coach to win three gold medals. i recently sat down with michael phelps and coach k in chicago at the global summit. we talked about their olympic memories, what it means to be the best at what you do, and the strategies they have utilized to achieve the remarkable performance. here is that conversation. let's start with you coach k.

what is the x factor? you not only have it in your life, but you teach it and share it with thousands of young basketball players. coach k: you expect me to give that to you right now? [laughter] charlie: i want to make my life better. coach k: right for the jugular he went. charlie: michael promised me he would teach me how to slam -- swim. coach k: he has a annual you are >> he has it and you are in constant search for it. it is great players and great teams that i have had the honor of coaching. it is much more than physical. it is basically that that person or that team does not have a point of failure.

they have interruptions, which knocked them back, but they will never accept failure in training, in competition, or whatever. they are just woven a certain way where they see, and in michael's case, the gold, they see themselves being great. in teaching you have to help them get over those points. whether it is lebron james or , or a number of guys that have it, i think if i had to say one thing, they are certainly talented and all that, it is that thing inside of them. sometimes you have to help them find that.

all of a sudden they go past the limit that they thought they had. all of a sudden there is another button. i just want to tell you it is an honor for a coach to sit next to him. i have coached more great players because i have coached the u.s. team for a number of years, then anyone in the history of a sport. he is as great an athlete that has ever been placed on this planet. he has done it not just for one period of time. i am not just blowing smoke. [applause] coach k: he has the x factor. charlie: and the olympics have

been around a long, long time. to have more than anybody in a long, long history of the olympics, says something important. what do you think it was? michael: along the same lines as coach says, i have been with my coach -- i have competed with my coach for 20 years. if you look at sports today, you do not find many athletes are with a coach for that long. you do not see it, right? you do not see it, right? i was trying to think of another athlete who has been with a coach for that long, bob and i started at 11 and from 11 to about 18, he would say jump and i would say how high. when he first met me at 11, he told me in four years i could make the olympic team. i stop playing lacrosse, baseball and focused on swimming. for some strange reason i decided to trust him and four years later i made my first

team. six months later i came back and i worked my tail off for those six months. i broke my first world record at 15. after that, we got to 18, we went to michigan for four years, that is when i started realizing that i could talk back. i never had that before. [laughter] michael: we kind of played with that a little bit. in 2006, he let me do it my way. at the end of 2006 i was not the happiest camper. 2007 and 2008 we changed it again, i can probably say today that those were the two best years i have had in my career. i just started trusting him again. of course we have our battles, but it all goes back to him pressing my buttons. we grew together as we both changed. some of the obstacles i went through, and he had to change how he approached me and how we worked together.

that was something that i really saw over the last two years that made us work as well as we did. these last two years of my career, i could not ask for a better finish. this is what i wanted in london. i wanted closure on the sport and closure on my career. when i hung up my suit i wanted to hang it up the way that i wanted to hang it up, not -- in 2012, i felt like i just wanted to get through it and i did not really care. taking the year and a half, two years off and deciding things of my own i think help me learn a lot. once i came back and i had to do it a certain way and i had to do it his way. charlie: was he there for the struggles? michael: of course. i have a lot of father figures in my life. and he was one of them.

i went through a phase where i probably saw my father five times in 20 years. that was a struggle for me. now we are finally at the point where we are friends and we are building a friendship again. i am so very thankful for the things that have happened in my life that have brought me to the point where i am today. this is how life should be. charlie: and you can build the relationship. michael: it is amazing to not only have them apart of my life, but a part of my family's life as well. charlie: after 2012 did you think you would come back in 2016? coach k: for him or me? one thing i would like to say. michael: we both said that. coach k: for him to be with one coach for that long, that is incredible because you are going

through different stages. i coach 18-year-olds who become 22-year-old and they leave. when i started coaching the olympic team 11 years ago, wow, it is different. the thing that you had with your coach and something that you want to build on all the time is shared a vision. at times, like when you are 18 or something, he saw a vision for you that you could not see. that relationship, whether it be business, family or in coaching, that is the thing i like the best. for me, it is not just a shared vision with a particular player, it is a shared vision with a group. we tried to manifest that in the olympics a certain way, and i do it a little bit, not a little bit but a different way with my

duke team. a shared vision is a really important thing. it is built on trust. can i ask him? charlie: if they are good questions. coach k: did you ever not trust your coach or question your coach? michael: i guess at 11, when i am 11 and he says you can make the olympic team in four years, obviously that is something gay -- that is something a kid wants to hear. at that point i was like, ok, this guy says he can do it so i might as well trust him. ever since then i think i might have trusted him. that is why i never left. he was the only one that i would swim for. obviously there were times that we butt heads and i threatened to leave, but that would never happen. something that was really cool that you said, shared vision, i think that was something he was probably trying to get me to see from the age of 11 where he taught me to dream as big as you can possibly dream.

i think that is one thing that i have lived on for so long. as an 11-year-old kid that i dream of being the best ever, yeah, everybody does. it is the sacrifices that i made and the goals that i had and the things that i had to do to be able to get to that point are even have that opportunity. i think that was something he taught me at a young age. he taught me how to set short-term and long-term goals. i do it every year. i was talking to you about michael she that i just found. -- that i just found. i have it hanging in my closet and i just found it. i was not very happy when i saw it. [applause] [laughter] michael: i hit one of my goals and i texted my coach and i told him the interaction my fiancee had when i was talking about it. he smiled and just said let it go. [laughter]

michael: it ended up being really good, but i think as i got older and older, i started realizing that there were so many people that doubted things that i wanted and i believe that i could achieve. i believed that i could go into 2008 and be perfect. i believed that, because i had trained for it and prepared for it. i was getting ready to do something that nobody had ever done in olympic history. i think just being able to get to that point where i believed in myself that i believed it could happen, it gave me the extra edge. i would not be able to win that race by one 100th. charlie: it was an important time in his life as well. wasn't he ready to leave and he saw somebody that has potential to be an olympic star?

michael: he did, he came to baltimore and he coached in cincinnati, he was helping for the 96 olympics and that is when we worked together. he saw something in me, a passion, a drive that i had. i was a little kid that was in his group swimming with 18-year-olds that would never let me go first. i was swimming through obstacles in a lane to try to make sure i was ahead of these guys. charlie: beyond focus and the mental attitude, how much of it was your own physicality? how much of it was that you had unique qualities as a swimmer? michael: broad shoulders long arms, short legs, a kind of works. i have tiny legs. i have very small legs. i think my body proportionally was good for swimming.

you see a lot of people who are tall, but their structure is a little different. my wingspan is six foot seven inches and i am six foot four inches. coach k: charlie, if he had long legs i would have recruited him. [laughter] a keyword you said about 12 and doing it until 16. one of the things we have in common is continuity. he had the continuity of having the same coach. with the u.s. team, and so much of what you guys do is you are big on culture. the culture that you have and the continuity of that. when we to go over in 2005, 2005,n we took over in there was no

-- that we could just win by putting 12 guys out there, and we were not winning. so over the last decade, we developed a culture, not just me but the players and everyone. , i did not want to give up on the continuity, but we built a something really good and i , wanted to take it another four years. i am a west pointer. there was an army officer. he and i are really good friends and he would take over, he is an air force academy graduate. so this summer, he spent a week with us in training, when we were training our olympic team to learn about how we do culture, and we became very close. as if i was in command, and now he is taking , over command. in the military, we want the next guy to do better.

then he will want the next guy to do better, and that is what we are trying to establish with usa basketball. he is great. i will try to help them. charlie: jerry, who brought you in, i think wants you to come and stay there and kind of be involved in the process. he also says he wants you to take over his job. coach k: no, i would not. i would not take over his job because he has to raise money. [laughter] coach k: i do not know how they do it, but in basketball, you don't get any money. you have to get into marketing agreements to support the sport at all levels. juniors, 17, 16 and all of that. and he is masterful at all of that. i do not do that. charlie: but you are going to stay with him? i will do what they need me to do. charlie what is the difference

: in coaching pros and colleges? coach k: coaching boys and boys who will become men. when i am coaching the team i help them cross bridges. bridges of maturity or improvement, and then you develop a relationship, because if you cross that bridge with that person, there is a bond. just like you did with your coach. in the pros, they have already crossed a lot of bridges. they have probably crossed some bridges that i would not want to cross with them. [laughter] coach k: believe me, or could not cross with them. let's put it that way. [laughter] it is just different. in college, they have to edge tapped to me and i adapt to their abilities. in the pros we adapt to each other. and we try to figure out a way where we all own it. i am sure that you all are trying to figure out with your younger generation. how do they own it, how can they feel it, how can they do that?

and we spent a lot of time with that really, and we include the armed forces so they can feel what it is to represent our country, and things like that. to me, you know continuity, , ownership, shared vision, ey- key,l k ke tea, things that you have to do if you are going to be really, really good. charlie: michael, you said you wanted to change. your goal was to change swimming. michael: it happened. at 15 i had this dream of completely changing the sports. both in the pool and out of the pool. i thought at that point that i wanted the sport to have more attention. because i think as a national team, we are probably the most dominating national team in the world. and, you know, for me, kind of growing up in the sport, things

that i was able to see and do in that sport, it changed my life. now, sort of being out of the pool, that is where the next chapter of my life is happening. 2001, i started working with the boys and girls club of america. children under the age of 14, drowning is the second cause of death. so i started working with them back in baltimore in 2001. in 2008, i opened up my foundation. kids who live healthy and active lifestyles and also teaching kids water safety. that is the only reason i started to swim. my mom put my two sisters and myself in the water specifically just to be water safe. this is what it turned out to be. [laughter] coach k: not bad. not bad. michael: i guess it turned out ok. charlie: all of a sudden parents all over america are seeing this and throwing their kids in the pool. [laughter]

coach k: especially the short leg kids. [laughter] charlie: but also what you have done is inspired kids. katie ledecky, you are her inspiration. michael: for me, this time for the olympics i felt like a dad. i honestly did, because i had been on the national team for so long, but also sort of, i felt like my role changed on the team. you know, you have the story of katie and i when she was 10. and we have a picture together. there was another girl on the team. she said she had posters of me as a kid. ryan murphy was the same thing. so you had these kids that have pictures that they got as a kid. and for me, it was cool, just being able to see them grow up into the people that they are now. for me, i am retired.

i am technically not retired, but i have signed the papers. i am retiring, so it is nice for me to be able to see the younger generation kind of take over. i also think back to the first gold medals. i guess the second night for me was the four by 100 free relay. and being able to swim with two rookies. i will never forget this moment forever. we are on the podium, listening right before the national anthem , starts and the two rookies are in the middle. really know not what to do, so i kind of said to them, i said, guys, you are allowed to smile. you are allowed to sing. and if you want to cry, just cry. i would say probably halfway into the song i hear somebody crying out of the corner, the side of my ear. and ryan just let everything go.

that was such a cool thing. to be able to represent your country at that level, it is the greatest thing in the world. for me, that is one of the biggest things i will miss. retiring from the sports being , able to wear the stars and stripes and represent your country like that has been the greatest part of my career. and these guys are taking over it is such an honor to see. ♪

♪ charlie: you have said before that you were retiring. michael: i will say it again. i have a beautiful baby boy any family that we are starting with nicole and boomer. i am ready, it i think that this time, i am actually ready. i think in 2012 i forced it. like i said before, i am able to finish micro like i wanted to. charlie: like winning the 200 meter butterfly? michael: that was, oh, my gosh. shadowboxing, i was kind of like, what the hell is going on? [laughter] michael: but i wanted that race really bad after he beat me in 2012, being able to come back and win that race, i don't often i will ever win. i just started wrapping my head around eight from beijing.

this started around a dream of winning one olympic medal. i had that first one in 2004, i will never forget that one. but being able to have this, it almost does not seem real. coach k: that is why it is the best ever. i am telling you. charlie: he talked about two things. he talked about pride in america. but the idea of pride is a positive quality. in a sense that i am doing this for something beyond myself. coach k: right, what we try to do with the olympic team is, each of these guys are a proud to be a part of that, so who are the proudest americans? ande, it is our military, because they not only protect

and serve us, they put their lives on the line. so we incorporate that. it is important for each of our guys to hear and see. but the most important thing is for them to feel. and if you feel, then you get it in here and you own it. we will do wounded warriors, we go to arlington cemetery. marty dempsey just retired as the chair of the joint chiefs. he spoke. we actually joined with the nba "taps," a group called tragedy assistant protective for survivors. the families who have lost a brother, sister, mother or father. and each of the cities that we have played exhibitions, when we did the national anthem, a taps kid was with us. and in chicago, we had a

ceremony in practice privately, where about 70 of them were there. and a number of them lined up at half court. and coachingm staff did and they had buttons , with a picture of the person who was killed. and they gave us their buttons. charlie: both of you have experienced failure. in terms of you having injury and with your back and going through a rough patch. the same thing for you. tell me about that. what are the lessons to be learned from that struggle? and the sense of recognizing that you are not all powerful. michael: yes. for me to become the person who i am today, i found myself in the darkest possible place that any human being could go. and that was the worst three or four days of my life.

of not really wanting to be here anymore. that is what i really got to, and for me to get to that point, it was like a downward spiral staircase. an express elevator straight down. and i put myself in that. for me being there and being did to come out like i learning a lot about myself and , learning how i work, there were so many things that i did not want to let out. and, you know when i went , through my struggles, i've literally came, and i just said, everyone will see the real michael phelps. and that was the coolest thing for me to be able to just be myself and not worry about if i will get judged. to just be exactly who i am. it was the hardest thing in my life. but honestly, i have had ups and , downs throughout my entire career. if you asked me today if i would change it, i would not. charlie: you learn from it?

michael: yes, and one thing thankfully, nobody got hurt in , any situation, but i am able to be the person who i am today. and for that, i have better relationships. i have better friendships. everything is -- is -- honestly, 10 times better. i am happy almost every day. it is just great being able, for me, being able to see my baby boy every morning is amazing. and just being able to travel and just enjoy myself. life today is how i wish life was for my whole life. charlie: mike? i think we all at times -- have times where you are down, physically, emotionally or mentally. i go back to being a cadet at west point. the two things -- there were a number of things i learned, but the two most in poor and things were failure was never a

destination and that you are never going to do it alone, so you want to be on teams and be with good people. and during those times, i don't know who did it for you, but that couple of times when i was really down, i had somebody strong enough to be able to tell me the truth. and i do not think you do it alone. someone has to tell you. so when i got real sick in the mid-90's, not just physically, but emotionally, my wife did that. and my wife said, look. going sou go, or i am , i went. if she did not do that, again we have been married 47 years. you know it is not like we have , problems in marriage, but at that point someone has to be strong for you because apparently you cannot be strong for you. and so i tell my guys all of the , time, be with good people. man, because somewhere along the line you will be better for being with them.

and in those times, that is where happened. with my wife, i have three beautiful daughters who will tell me the truth. they are not beautiful all the times when they tell me that, but they will tell me. michael: i think that is also something that is so true. like i always felt like i could , do anything on my own. it is almost like, you know, at that i guess i had to learn it point, was ok to ask for help. when you needed it. and i think once i learned that, i was like wow, this is how life is, this is great. charlie: you can admit that you were vulnerable. michael: that was just the greatest thing. being able to pick up the phone and call somebody and not feel bad asking for help. because what is the worst they can say? sorry, i cannot help you right now? coach k: which they won't. michael: yes, i think that was something awesome to learn. charlie: what are your goals now? michael: i think that is also

one thing i am excited for now because i always go back. four years ago i was not ready to go forward. for me continuing to change the sport, even though i am not in this pool, it is what i am figuring out. my biggest thing is, if you put me -- i want to work more with children. if you put me, no matter what kind of mood i am in how many , hours of sleep i have had, if you put me with kids, you will see the real me and the genuine me. and that is where i plan on doing all of my work. charlie: what is the hardest thing about winning five ncaa championships? i think the hardest thing is that you only need one pickup --hiccup. when we coach in the olympics we have to teach them, it is one and done. once you get to the medal rounds, you do not have a do over.

they are having a thing where they do have do-overs. they could look bad on the second game of the series. how do we be really good all of the time? i think a huge thing for me is that we have different teams. like i have a different team every year. year, because of one and done. in our sport a kid can leave , after one year to go pro. we have to continue to teach our culture. we used to have juniors and seniors teaching it, i do have that this year, which i think we will be really good. a big part of it is that i have that secure, upper-class leadership. but how do we -- how do we maintain the culture of going after the national championship? and that is what we have tried to build. at duke.

we have done it with the olympic team. culture takes over a lot of times in competition. you made a number of interesting points great points. , one of them was, you took pride, i don't know if you caught it the fact that it was , not about his gold medals, but u.s. swimming has been a dominant. you are part of a great culture. you are a big part of that great culture, but you are still part of it. and so when you go out there, , you are not just competing for you, you are competing for the culture. and if you can get that, we have a better chance of winning. that is what i -- charlie: i was thinking about the equivalency for people in this audience of doing what the live you have done. but especially michael has been in the olympics for a long time. what is the equivalent for what michael has done in corporate

america or in the world of wall street and finance? in building the greatest company that has ever been in at the same time creating the greatest , product that has ever been? or creating the most innovative financial model that has ever been or changing the way we , generate the contributions of financial communities and corporate communities to the overall global economy. all of that. i mean when you think about what , the two of you have done and have done it over a lifetime, that -- people have said to me before, it is difficult to win one, but to win 28, to win five, that is the hardest part. is the first one the hardest? or is the last one the hardest? coach k: i think each of them are. i think the fact when you do it the first time, you have a of that youevel know you can do it again.

and then, it is a matter -- it is a matter of do you want to do it again. are you willing -- that is why so many people do not do it multiple times, because they do not have the same hunger. that is the thing that i am saying about you. is that, over five olympics, ok. how did you stay hungry? we were taught -- he and i were talking like a coach and son speaking of what makes him tick and trying to take that back. [laughter] coach k: so i asked him, so he is in competition, ok? when you are on a court, you feel things. you are in a race, how do you know where other people are? charlie: yes. when you are swimming, how do you know who is swimming

next to you? michael: you can feel it. obviously it is like when you , are in the pool, the middle lane is the fastest lane, the rightastest people are next to you. you have a sense of where people are. some strokes you can feel the splashes. coach k: that is crazy. [laughter] coach k: it is nuts, really. splashes.ing the michael: i just have a sense of where things are. the biggest thing is i know if i am prepared nothing else , matters. if i have done the work, i know no matter what happens -- charlie: 100% of the time are you prepared? michael: no. charlie: and if you are not prepared, why not? michael: in 2008, i was probably not working out 100%. i was not at 100% in 2008.

i probably won those eight gold medals on about 80%. six monthswrist before the olympic trials. i was literally in a cast two days after i broke it and i had to figure out how to get pressure back on the hand. and that was right before trials. so i had to do it again at the olympics. i think this time in 2016, it was probably the first time completely giving 100%, being at every workout, sleeping the way, doing the right things away from the pool. a couple of coaches always say, nothing good happens after midnight. i am in bed before midnight. so all of those things i did before, going into the olympics, because i knew i had to do it the exact way. coach k: i love being in the moment of a great team or a great player.

you mentioned that about your coach. that is why i still coach. mackerel iause, holy , can be any moment of this 20-year-old guy who wants to be the national player of the year right now or this team wants to win its first national championship. and to be in the moment, you have to be in the moment for each of your races, right? do you understand what i am saying? michael: yes, i do, i do. coach k: do you do any visualization? charlie: explain the visit visualization. coach k: as a coach we try to teach that, in other words we will practice something and we have everything on tape. i might put five sequenced tape together on their ipads. i say this is how you should look. when you look good this is how. , then watch that, then don't watch it and watch it in your head.

you know, like at different times, visualize this is how you should look. phasest this, but strong , how your body language -- you should not just play like a great player, you should walk like a great player, you should look like a great player, you should act like it. and we tried to -- we actually spend a lot of time on it. michael: it is funny because, for me, i was taught at a very young age by my coach to prepared to do that. i would do relaxation stuff when i was laying down, trying to shut every -- when i am going to bed there was a relaxation process that i would go through to help me to relax and to help me to go to sleep, but also, i play how my race should go, how it could go, and how i don't want it to go.

so whatever happens, i am prepared for it. charlie: on behalf of our audience, a great thanks to these two great champions. michael phelps. [applause] ♪
