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.

Ask yourself: What forms the decisions you make? What is it that gnaws at you? What are your crucible moments?

I think I have terminal curiosity. So I always think that the future will be better and different than the past. As I look back and take inventory of myself, I'm very open-minded and flexible. People say the older you get, you get set in your ways. I don't think so.

If you start painting yourself into a corner, life starts shutting down. There is always hopefully a next.

As an entrepreneur, you work out solutions.

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.
