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.

I think finding the way in life is the hardest part. At every stage of life, every trial, every success, you know, you're going into some kind of fog. There isn't a plan that suddenly reveals itself, and you go, "Ta-da! Now I understand."

I think different societies, cultures, individuals, teams of people, make the world a better place. The founding fathers, they made New England, they made those 13 colonies. I don't know if they thought they were changing the world or just changing their world, but they did make the world a better place. Doctors that cure patients or cure diseases or make discoveries, they're making the world a better place. Can I make the world a better place by selling underpants? Not really. That's just the means. That gives me resources to try to make the world a better place.

I think I'm determined. And I think if you're determined, you're right. Your behavior is exactly the same when you're stubborn, except then you're wrong. And so, there's times when I'm wrong, and I'd say, "Well, you were the dark side of determined." But I think determination, you know, it's like have an idea, think about the idea, the risks involved. What does it take to get from here to there? And then once you make the choice, you just keep going.

My mom was terrific. I described my mom once. If fear was a color, she was color blind. Nothing frightened her. If I told her that I was going to take over General Motors, she'd say, "You can do it." Just the most preposterous things, ambitious things, she said, "You can do it."

When you coach and teach leadership, most people think about them. It's like you're the leader and how do you influence them. Clearly, leaders do take their followers, their flock, their enterprise, their business - whatever - hopefully to a better place. But I think the foundation of what makes really great leaders is they lead themselves, and they're conscious about knowing themselves and coaching and leading themselves in a very profound way. The simplest of us talk to ourselves. The question is, "Do we really lead ourselves?"
