That's the most terrible mistake you can make: to relax. It's difficult to become a champion, but it's more difficult to maintain it for many years because you're getting too comfortable.

I'm playing right now a role, and the role is called the 'Heavyweight Champion of the World.' And it takes all of the time. And I love this role, and it takes a lot of attention for me for the sport, and I just don't want to lose the title, so that's why I have to stay focused and not become an actor.

I Was Psychologically Sick For 3 Days Afterwards.

On your way to the top, you always get some chriticism. Criticism is a great motivation.

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

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.

All of my fights are planned. I study my opponents from A to Z. How he walks, how he looks, how he speaks, gestures of the human body, which is a certain language that provides you lots of information if you have the ability to read it.
