Golf isn't a sport, it's a game. I'm not saying it's not a difficult game, with lots of mental stuff. But it's not a sport like mine. Where is the combat, the intensity of what we do?

The surface below your feet is so special. It is not like a boxing ring, not like a wrestling mat, it's its own thing, and when I am there, I am floating, I am moving with total freedom, I am free. And when you know, when you just know you are going to win, like I do, there is no better feeling.

I daydream too. I visualise. I think ahead, I can do it now, sitting here. I think ahead to the walk-in, I can hear the crowd, the music, I can feel the cameras all around me, I can feel movements in my body as I am heading there, I can bring up that incredible feeling you get when you step into the cage.

To do anything to a high level it has to be total obsession.

Doubt is only removed by action. If you're not working then that's where doubt comes in.

When I'm in there I'm just in my zone. What people think about when they're looking at me, that's their business. If there is a bit of that, I am fine with it, each to his own.

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.
