'm so fortunate to have done what I love to do for so long, but the day I retired was one of the best days of my life. Not because I was happy to get away from the sport, but because it was clear in my mind that I had done all I possibly could, and that it was time to go.

An athlete and actor are really two different temperaments, night and day. As an athlete you really keep things out and as an actor you really bring things in.

When I run - you can see my record - I run to win.

Every New Year's Eve, I have a pact to do something I never thought I'd do. So I created this list. You have to free your mind to do things you wouldn't think of doing. Don't ever say no.

Most people want to become movie stars and I just want to be in the business. I already was a star. If I get the part of a lifetime and it blows up, then that's wonderful. But if the acting doesn't work, fine. I'll just be a producer. And if the producing doesn't work, fine. I've got a lot of other stuff.

I'm not supposed to be able to speak clearly, and decipher what's going on in the media. I'm supposed to be the typical amateur who's 22 and scared to death and can't believe he won the Olympics.
