The first thing I learned in boxing is to not get hit. That's the art of boxing. Execute your opponent without getting hit. In sports school we were putting our hands behind our backs and having to defend ourselves with our shoulders, by rolling, by moving round the ring, moving out feet.

I'm boring but effective.

Mental strength is really important because you either win or lose in your mind. And I'm not solely talking about sporting matches, boxing events - anything you do, you do it first with your mental strength. And you can actually train and develop it, and I am responsible for what I'm saying because I have experience with that.

I should say that mental strength is No. 1, experience [is] No. 2, physical strength is No. 3, and genetic ability that you're getting from Mother Nature probably comes after.

It's not my place to compare myself to greats like Tyson, Frazier or men like that. But I would look at a fighter like Evander Holyfield. He's a great heavyweight who worked his way up through the weight classes to become champion and had to beat bigger men along the way.

Earlier in my career, I never thought of boxing as a chess game, but I confirm that they are, in fact, very similar. You can plan your fights and strategy just like you would in chess.
