There's nothing to fear but fear itself. It's an illusion of fear. Fear is an illusion. If you gonna die, you gonna die anyway; it's not something to fear, fear is not gonna help.

I fight for perfection

I hope I can improve. I'm far from perfect. Sometimes, I wonder what would happen if I fought myself. I think it would be a one-round KO. But if I was fighting myself, I know I could take my best punch. No, make that two rounds. I would knock myself out in two rounds.

It's the emotional punches that you can't see that are just overwhelmingly devastating to your heart - your moral fiber.

I ain't the same person I was when I bit that guy's ear off.

There are nine million people who see me in the ring and hate my guts. Most of them are white. That's okay. Just spell my name right.

I'm a good friend, but I'm a hell of an enemy. As your enemy, I want your demise. When I feel that in my heart it burns till I die.
