I don't know why I run so fast. I just run.

By the time I was 12 I was challenging every boy in our neighborhood at running, jumping, everything.

But when you come from a large, wonderful family, there's always a way to achieve your goals.

The triumph can't be had without the struggle.

'I can't' are two words that have never been in my vocabulary. I believe in me more than anything in this world.

I ran and ran and ran every day, and I acquired this sense of determination, this sense of spirit that I would never, never give up, no matter what else happened.

The feeling of accomplishment welled up inside of me, three Olympic gold medals. I knew that was something nobody could ever take away from me, ever.
