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.

You never lose until you actually give up.

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.

Discipline makes hard men. Every hard man is capable of being a killer. But every killer is not capable of being a hard man. They can't endure that much. It's all about the endurance. That's why they become killers. Because they can't endure the pain. They need to kill the pain to stop it.

Every win, regardless a good or bad one, gives you more confidence.

People love you when you're successful, but if you're not, who really cares about you?

You have to have a bunch of dimensions [of yourself]. You have to be able to adapt in this world. You can't be a nice guy living in a world of savages.
