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.
