People can do more than they ever believe they can do. Physically, mentally, academically. You have to be pushed. It hurts. But it's worth it, and it's a great thing.

I wanted to be like Bruce Jenner.

I only wish that I had had the courage and the knowledge to have gotten that out of my system, out of my mind or my heart years earlier. But there is no book, there is no manual to tell you how to deal with sexual abuse.

To be the best, you need to spend hours and hours and hours running, hitting the speed bag, lifting weights and focusing on training.

Although it was a great accomplishment to win a gold medal, as soon as they put it on you, that's it; your career is over.

I've never believed in tying myself up in a long-range contract, and I've been very outspoken on that subject.

My ambition is not to be just a good fighter. I want to be great, something special.
