If you did everything your mind told you to do, you do some really strange stuff. You'll probably be in jail, you'll be in trouble. But, it's all about control. We all have to control our feelings. That's the thing that separates us from animals.

I know at times I come across like a Neanderthal or a babbling idiot, but I like that person.

It's nothing personal, but I'm going to kill this guy

It's unnatural to fight somebody who has nothing against you and never did anything to you or to your family, who never stole anything from you. And now you've got to go and try to dismantle this guy.

Cus was my father but he was more than a father. You can have a father and what does it mean?—it doesn't really mean anything. Cus was my backbone . . . . He did everything for my best interest . . . . We'd spend all our time together, talk about things that, later on, would come back to me. Like about character, and courage. Like the hero and the coward: that the hero and the coward both feel the same thing, but the hero uses his fear, projects it onto his opponent, while the coward runs. It's the same thing, fear, but it's what you do with it that matters.

Boxing is an ego-driven sport. The idea is to not get too personal or emotional with it. You just know when it's over, it's over, and that's it.

I'm a bad guy. But if I was a good guy, nobody would want to pay to see me fight.
