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?

It makes a difference when you've got more than two months versus two weeks to train for a particular opponent.

I believe in believing.

I studied every move, I became fascinated by thinking what I could have done differently. And I take that approach now as a professional. I am on it, all the time, never stop thinking, learning. You don't get to be world champion unless you do that.

I believe in working harder and putting in the time - being completely obsessed. And, yeah, I think that's life.

I am not a big crier. But I'd say it was after the Mendes fight. It was not because of the fight as such. It was everything leading up to it. It had been such a tough time. When I did my knee, I had some very dark times. Life is all about ups and downs and I'd say there had been a lot of downs, but I got through it, I won and after the fight, I was standing in the shower and I was crying, just letting it all go.

I don't watch the news, I don't care about politics, I don't care about other sports.
