emily: tracy sun, posh mark cofounder, and a very generous posh mark.arag, mobile director for stub hub. steve, who i hope has security as he leaves the building -- richard branson, coming up. ♪ emily: work family, life. as a working mom, i know how hard it is to juggle these responsibilities. that is why i was oh excited to sit down with facebook ceo sheryl sandberg and virgin group cofounder richard branson about this balancing act and whether we can all have it all. sheryl sandberg: one of the reasons i wanted to be here with richard, he will say this is good for my company. we do not have enough diversity at facebook. the reason we want more diversity, we will build a better product and a more successful company. i think what will motivate business and organizations to take diversity seriously is when they realize not taking diversity seriously is harming performance. emily: what is the next phase? what conversation do you want people to be focused on now? sheryl sandberg: it is about the culture. we will not get to quality until we change the idea.
