You have to know you can win. You have to think you can win. You have to feel you can win.

My toughest fight was myself. For me to disclose and let things out was not easy because we don't want to seem weak or like we are different, but I learned that it's okay.

Except for Ali, fighters had never been marketable.

They say that I'm stubborn, and my wife says that, too, but it's paid off so far.

I retired and came back in '97. Woo! I mean, come on! I don't know, man. A six-year layoff? That was crazy! My career was relatively short, whether you look at either its length in years or the number of fights I had. But it was brutal.

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.

I've always been quiet and kind of shy. I'm sociable, but I would probably migrate to a corner.
