Anger is my biggest enemy in life.

[Sometimes I] put on a ski mask and dress in old clothes, go out on the streets and beg for quarters.

This white woman came up to me, and I'm thinking, WOW. When I was a kid, she would have been robbed and raped and left for dead. This is a real strange scenario, and I just wanted to cry. I'm like, "Who am I? Where's my heritage?

I'm the biggest fighter in the history of the sport. If you don't believe it, check the cash register.

These books ain't window dressing. I think Machiavelli's the most sophisticated writer outside of Shakespeare. Way ahead of his time. Such a manipulative person. Everything he accomplished he did by kissin' ass.

I was an emotional manipulator of fighters . . . You have to know how to be cold, you know? Just have no -emotions, no feelings. It takes time, though, to develop that. I'd been working on that since I was 12 years old. It doesn't happen overnight.

The one thing I know, everyone respects the true person and everyone's not true with themselves. All of these people who are heroes, these guys who have been lily white and clean all their lives, if they went through what I went through, they would commit suicide. They don't have the heart that I have. I've lived places they can't defecate in.
