I realize that I'm in the twilight of my career.

I was always really strict on myself about doing everything possible to prepare for competition.

I think I could look back through the past few years at missed opportunities and stuff, but one thing I have learned is not to dwell on missed chances or times where you have failed.

That's what really seems to be the more difficult aspect - to have the men break through and challenge the best players in the world.

Totalitarians always want to kill culture. But imagine life without football, Faulkner, or Bob Dylan. It's not life.

I could have been banned. That's what I was most scared about. All the hard work being for nothing. It was basically my livelihood and my sport being taken away from me. It was everything.

We wanted Nike to be the world's best sports and fitness company. Once you say that, you have a focus. You don't end up making wing tips or sponsoring the next Rolling Stones world tour.

I got picked on a lot. I was a complete geek in school. I had braces. I didn't have the hot girlfriend. I wasn't ever sought after. I was a stocky, awkward kid who got laughed off the tennis court when I tried that.
