i think if you just read david hackett fisher's book you get an appreciation for how he saw possibilities and opportunities which i think is a very important quality for a military leader when others only saw difficulties. right? and i think that's because he had also been a student of war and warfare. he obviously had an experience during the french and indian wars. but he really developed his ability to lead by reading and thinking. so i think across all three of these leaders is a commitment to learning the profession and studying war as sir michael howard said to study it, in width, depth, and context. so one of the things we're emphasizing in our army obviously is inculcating in our leaders a desire for lifelong learning and for reading and thinking about -- think about how arrogant it would be if you don't do that. essentially you're saying all i need is my personal experience and i'll be able to figure out any wartime situation. of course not. you have to read and think and learn continuously to be a true professional in our military and in our army. >> wonderful answer. okay. why
