Boxing is limited fighting with a specific rule set. Fighting is true, where you can do anything.

I'm already the face of the UFC, plus the face of boxing, WWE, and Hollywood.

If they let people go fight jiu-jitsu tournaments, they can't stop me going to fight a boxing fight.

People say that I'm a boxer. I actually started with kick boxing, and then I moved onto boxing, and then I moved onto grappling.

I don't feel bitterness, I don't feel anger towards anybody. Fighting is never emotional to me.

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.
