I've been fortunate to meet and work with a lot of really smart people. The thing that strikes me most about them is how they continue to explore and learn every day. I have tried to apply that approach in my modest career as well.

My father once told me that anyone who worked for three dollars an hour owed it to himself to put in four dollars' worth of work.

To me, the most important part of winning is joy. You can win without joy, but winning that’s joyless is like eating in a four-star restaurant when you’re not hungry. Joy is a current of energy in your body, like chlorophyll or sunlight, that fills you up and makes you naturally want to do your best.

Success is a result of consistent practice of winning skills and actions. There is nothing miraculous about the process. There is no luck involved.

I don't have very many regrets, not because I lived a perfect life but because life is a bunch of rolling hills, not mountains, or speed bumps instead of stop signs, and so you come to a situation and it's neither good or bad, it just is, and what it means to you is what's your take on it. But the second part of the equation is what are you going to do about it. A lot of times I'm completely wrong, but all you do is back up and start over.

If you can take something to levels that very few other people can reach, then what you're doing becomes art.

The last five or six days, I've been running. The last two days, I've been running pretty hard. Everybody's got to be someplace.
