I had two ACL injuries in my life, and both of them happened when I was training with bigger guys; a heavyweight and a light heavyweight. Sometimes it's not even because the guy is good, you just get hurt.

Nick Diaz is a champion so he's got the spirit that comes with it. So he's not going to give up mentally. You see a lot of guys give up mentally and that's why they get knocked out or submitted. They give up mentally before they lose.

If you prepare your subconscious for highly stressful situations, you can create harmony with your fears. You can tame fear like a wild animal and use it to your advantage.

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 like life. The more knowledge you get, the more questions you ask. The smarter you get, the more you realize that everything can be possible.

I will never take the fact that I am Welterweight Champion for granted. I learnt my mistake in the past. No matter how great, no matter how people tell me how great I am, I'm always one mistake away from losing everything.

I don't want to be an exception, because I was very outspoken about Performance Enhancing Drugs. It would be bad for my reputation if I would have an exemption [for doping test] - I don't want to have a free pass, I want to be like everybody else.
