A guy that has more knowledge has the advantage.

To fight a bigger guy you need to train with bigger guys and it takes a lot more on your body. And it's not your weight class.

I am a public person and I have my private life. It's important for me that my private life stay private, that what I share with the people is my public personality.

For me there is no reason why to go up in weight class, because when you go up in weight class you have to fight bigger guys - then you have to train against bigger guys. The guys are not better, they're heavier, but it means you have more chance to get hurt.

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

The danger is not to set your goal too high and fail to reach it. It’s to set your goal too low and reach it

Respect your opponent, just make them respect you more.
