The real test is this one: When you're alone in a room, when you're in a private place and nobody else can see you, what do you choose to do? Eat well, or eat poorly? Exercise, or watch television? Practice something, or do nothing? The best version of the truth appears to you and you alone, when nobody else can see. This is the test of discipline, and it's what makes the difference in your life. It's what regulates your own system and guides it. The individual alone comprehends it.

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.

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.
