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.

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

Boxing is the ultimate challenge. There's nothing that can compare to testing yourself the way you do every time you step in the ring.

No one but myself thought I could beat guys like Tommy Hearns or Roberto Duran

It's hard to talk about yourself.

I think I've become one of the best finishers in boxing; if I hurt a guy, I normally take him out.

Before I fight, I always pray that no one gets hurt.
