My favorite leader is George Washington. Because he came from very modest circumstances. He wasn't the son of a plantation owner. He was the son of a farmer. He had no formal education, very frustrated. He started writing a diary when he was in his teens, and he wrote things like, "When I grow up, I want to be respected. When I grow up, I want to be successful. When I grow up, I want to know things." What I find fascinating about Washington is he wanted to make something of himself.

I think what I've tried to do is make the world a better place. I think that's what's really important. Nobody remembers who sold the most togas in Rome. In terms of legacy, people remember the great villains more than they remember the great heroes. So I think how you feel about yourself is the most significant question. What do you say about yourself when you put your head on the pillow? Are you really proud of what you're doing and the way you're doing it? I think it's really a fundamental question.

I think it's good to have your own selfish interests, whether it's liking chocolate ice cream or wanting a new car. It's just human nature is that. We have our own selfish interests. I think we have interests that go beyond our self to friends, to family first, maybe to friends, maybe to community. I think that's important to think about those spheres of influence that radiate from you.

I think success is about purpose. People ask about success at different points in your life. As I look back, I think people that are successful feel good about what they are doing, and they can look back at what they've done and they feel good about it. People sometimes ask about success and they say, "What's your legacy?" and I say, "I think it's really a dumb question." I think the question is: What am I doing now? Do I feel good about myself? Am I proud of myself? Whatever purpose there is in life, I think success is about purpose. It's not about material things.

I don't think most analysts understand that whether I work a 70-hour week or an 80-hour week, I take my head with me when I go home.

I was single for most of my life. The best thing that happened to me is my wife. I've got four kids. All of them go to Harvard. Much better than their dad. They're really bright kids.

You’re not going to be a 1.000 hitter all the time. You’re going to be more wrong than right. You just have to correct your errors as quickly, as economically, as possible.
