Criticism is a great motivation. Failure is not an option to me.

You can take your fitness seriously, but not yourself. That's the most difficult part: not to relax. That's the most difficult challenge I'm facing every fight.

My height is an advantage, if I want to use it.

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.

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 don't like to get hit, who likes it? I probably wouldn't do this sport if I was getting hit that much.

I think we have tremendous media covering the sport of boxing, even if boxing is a little bit lost in popularity with MMA sports. And I think that with the show 'Lights Out' it's going to get more attention to the sport, and it's going to put more attention to the problems that athletes in general have.
