I am not going to allow myself not to perform well just because I don't feel well. I am bulletproof to the extent that a lot of things can be thrown at me, but it's about how much I am prepared to let them affect me.

When I go out and race, I'm not trying to beat opponents, I'm trying to beat what I have done...to beat myself, basically. People find that hard to believe because we've had such a bias to always strive to win things. If you win something and you haven't put everything into it, you haven't actually achieved anything at all. When you've had to work hard for something and you've got the best you can out of yourself on that given day, that's where you get satisfaction from.
