My mentality is that when I go to sleep at night, I'm a better martial artist than when I woke up in the morning.

A guy that has more knowledge has the advantage.

Fighting is about knowledge, knowledge is a very important part of it.

I don't want things that I regret in life, and things that I have not done - and I don't want to at 80 years wake up, and tell myself: 'Oh I was on top of my shape and skills and I didn't do it.'

Dana White came out very often in public saying I'm this and that; I'm sure it's also to play with my ego, to make me, for example, come out of retirement and say 'Oh ok, I'll fight for peanuts.' No, I'm not like that. I know the game.

People have mistaken my break, I took a break from competition, it was because of mental problems, and because I was not agreeing with Performance Enhancing Drugs. I put the things on pause for a while, but I didn't retire.

It's not the most powerful animal that survives. It's the most efficient.
