That's the way to go. People say: 'Oh, he doesn't want to come back, he's scared,' and it's to play with your brain, to play with your mind. I'm not scared of nobody. I'm not scared of no human being. I'm scared to fight, every time I fight I'm scared, but I'll bite into my mouthpiece and I'll walk the walk.

It’s OK to get butterfly in your stomach; the key is to learn how to make them fly in formation.

Fights aren't won in the octagon, they're won in the months leading up to them, in a near-empty gym, in the lost hours of a day, whether I feel like it or not.

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.

My fear delivered one of the great lessons of my life: That someone without fear can’t push himself. He can’t get better. He can’t transform negatives into positives. He can’t open his world to creativity and invention, or even progress.

What happens when you accept and embrace your fear? Fear becomes your weapon.

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.
