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.

When I decided to go for four gold medals I planned it out over a few years. It was in four different events and there was a lot to it.

My best performances were when I was 30 years old, and I was a vegan.

If you don't have confidence, you'll always find a way not to win.

I don't feel I'm qualified to be a coach outside the high school level. I think I would need to do more education to really be a good coach.

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.

I've always known that sporting people frequently suffer from joint problems because of the repeated strain they put on their bodies to get to the top. But somehow I never thought it would happen to me.
