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.

Growing up, I knew you were supposed to have a profession - and something better than being a shopkeeper, which is what my parents were.

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 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."

Sometimes I wish I lived more in the day, but I'm happier thinking about tomorrow or the day after. The way I see it, there's always a new or next thing.

My friends don't understand, whether it's belonging to a country club or playing golf, or whatever a vacation is, that should make you happy. And it's like, "No, happiness is much deeper." I think people have to struggle to find things that give them purpose, the real meaning. Why am I alive? Why did God bless me with these skills or these resources? What am I to do with them? If God just lets some person be very fortunate, let's say financially, it's kind of a funny God.

As an entrepreneur, you work out solutions.
