All the champions - you go and ask Mike Tyson or Joe Louis, Rocky Marciano, Lennox Lewis and myself included, and I'm sorry for putting myself in line with all the other great names - but the champion's attitude is it doesn't matter who is in front of me, I am going to conquer this person and win the fight and knock the person out.

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.

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

It's such a gift in my life to be able to compete - to have the health.

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.

I've been many times to Dubai and the U.A.E., and I have friends that live there. It would be exciting to stage world heavyweight championship fights in the Arab world. It's something Muhammad Ali achieved when he fought in Zaire or the Philippines. It's absolutely exciting to fight in countries where you have never fought.

From nothing to everything is a long way, from everything to nothing is one stop.
