If you keep your nose to the grindstone, you don't have any nose.

Society can't wait. It's sad there are so many entrepreneurs, business successes and venture capitalists who give no thought to society.

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."

The risk of failure is a very personal thing. One of the quotes I like, I think this came from the famous basketball coach from California - John Wooden - is that, "Successful people - winners - do everything necessary to prepare to win, without the certainty of winning." Everybody would do everything necessary to prepare to win if winning was a certainty. So you're willing to put yourself out publicly and privately and say, "I'm going to do this."

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?"

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.

You have to keep being curious. The notion that the present is different than the past, and the future will be different than the present, and the present is past, as we say it. I think I, by nature, am an optimist. Maybe I was driven to escape from my childhood and to be something, create my own world or career the way I wanted it to be. And I keep doing that in very interesting ways.
