There's certain things that you cannot cross, no matter who you are, what you're doing or where you're coming from.

In the old days, when Muhammad Ali was fighting Ken Norton, Joe Frazier and George Foreman, there was a lot of excitement in the heavyweight division, I have to admit it.

I think that boxing is actually not as dangerous as the politics. In boxing, you're gonna get a bloody nose or a black eye. In politics you can obviously get either dioxin in the food or bullet in the head.

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

You lose or you win the fight - and anything in life - in your mind. I can look at how the person walks, how he speaks, his expressions. It's a wisdom. Eyes are the mirror of the soul. So you can read a lot.

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.

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