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.

My very best memory of Montreal was the moment inside the Olympic arena when I was waiting under the stadium and those majestic gates opened up. It was a whole other world.

I found boxing when I was 14 years old. I went down to the gym because my brother, who used to beat me up all the time, introduced me to boxing. I found boxing to be a sport that I felt safe in because I controlled what was in those four squares.

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 always expect unexpected challenges.

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

You don't play boxing. You really don't. You play golf, you play tennis, but you don't play boxing.
