I will cross that bridge when it comes. I am not stupid. I am a very bright guy. I know that in the fighting game, you get people who get brain damage and do themselves long-term harm. I am into it in a big way, and I am good at it, and I am going to get very, very rich and then I will get out and we will see what comes after that.

Boxing is going to have to catch up with the kind of things UFC is doing. They're getting left behind.

I don't give a f***. We're not fighting. I don't care what anyone thinks about me. All the stuff I have to do outside the fighting, the promotion, this, I don't give a f***. But when I am facing up for a fight, I know what they're thinking. I can read their minds. When I am going face to face with an opponent, nose to nose, I can smell the fear, and I'm feeling no fear at all.

My diet is usually pretty consistent whether I'm training for a specific fight or not. I don't like to mess too much with it.

A fight is mental, not just physical and psychological warfare is absolutely part of that.

{Losing can be a great motivator] but not if it drains your confidence. One of the reasons I got into this game was because I wanted to learn how to get myself comfortable in uncomfortable situations.

I am in the fighting game, I don't care about anything else. I don't watch the news, I don't care about politics, I don't care about other sports. I don't care about anything I don't need to care about. This is my sport, it is my life. I study it, I think about it, all the time. Nothing else matters.
