Our time on Earth is already short enough. For me, it's like every single day I try to be as happy as I can. It's crazy to think about. We never have enough time. That's always the thing. We always want to do more. So it's about being able to spend time on the things that are most important to you. Life is a lot easier that way, and obviously life is pretty difficult a lot of the time.

When I race, I don't think about it; it just happens.

I know it won't be eight medals again. If you want to compare me to that, that's your decision, not mine. I'm going out there to try to accomplish the things that I have in my mind and in my heart.

There is a one woman in China that claimed she paid $50 to get my e-mail address. It was pretty shocking. I got one this morning from Scotland. A girl's requesting a signed photo of me.

Nothing is impossible. With so many people saying it couldn't be done, all it takes is an imagination.

I think sometimes I guess you see records, say you want to get there and use that as motivation. In a way, it's kind of cool if there is a possibility to rewrite history and be up there with the greats of Olympic history.
