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.

Sometimes you have to wait for the right deal. They all seem good, at least at first, and they may make you some quick money. But when the right deal comes, and it fits into your [overall] plan, it's just overwhelming success. Sometimes, with the long-term deals, you have to take a risk if you're going to get a reward. It's exactly like fighting. Sometimes you have to take chances to get that huge win.

I felt the same fear in my first fight as I did in my last fight. It never goes away.

Emotion is more than just anger. When I am performing, I need emotion, but I need control, too. Emotion drives the best performance and is necessary, but it must be controlled. I believe Fedor [Emelianenko] does that. I do too. We may look different in how we do it, but we both do it.
