I am proud to be in Los Angeles. I have a lot of fans that love me here. When you talk about the Meccas of boxing - Las Vegas, New York - now you have to talk about Los Angeles.

Recently I donated money to the establishment of the Muhammad Ali Foundation in Louisville. I regard that as a kind of payback. He smoothed the way for us. He wasn’t just a great person who had conviction, but made the sport of boxing great. He was the first superstar, he made our stock rise. Without him we wouldn’t have earned so much. Americans from every walk of life have contributed to the foundation: Bill Clinton, Angelina Jolie, Brad Pitt. Unfortunately I was the only American athlete to make a donation. There’s not enough respect in our business.

For me, there's never any bad blood - unless you do something to me.

Adversity is something that makes reaching your goals so much more rewarding than if it didn't exist.

I come across famous people all the time. It's the respect factor I appreciate. They respect me, they respect what I've achieved and the manner I've done it. It's street credibility. They know where I'm coming from, they know my reputation.

If you’ve got physical weaknesses, you’ll lose. Nobody who gets cut easily can be a champion, however strong and talented he is. Boxers are trained to see and exploit their opponents’ weaknesses, they hit you on your wounds. Only the strongest survive in this sport.

After about 25 fights you don't always have to keep going to the bathroom before the fight.
