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.

Man is not meant to be humble, he’s meant to be humbled.

I normally don't do interviews with women unless I fornicate with them.

I don't have to be that gentleman ["baddest man on the planet"] anymore. Now I have to be "this" guy. And in order to be "this" guy, I have to be smiling, I have to be gregarious, I have to be entertaining, and I have to be friendly. This is what my career needs now. I've adapted. But 20 years from now, I may need a different persona.

Without struggle, there is no progress. There has to be struggle in your life. You have to grow in experience to control your ego. Cause, you know, an ego can be crushed, it can be killed, it can be smashed, but it comes back. It never dies. That's the thing about the ego: it never dies.
