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.

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.

Train smart at all times and do your best to avoid injury. Training smart is more important than training hard.

It's not about how you are when things go well, what defines you is how you are when you fail from an obstacle.

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.

If you want to be a proud person, then you want to avenge your loss. For me it was [Josean] Serra and [Joe] Hughes, and for Michael Bisping, Henderson is one of his losses - one of his most painful losses. So I understand why he wants to avenge it. As an athlete I understand.

As Aristotle wrote a long, long time ago, and I'm paraphrasing here, the goal is to avoid mediocrity by being prepared to try something and either failing miserably or triumphing grandly. Mediocrity is not about failing, and it's the opposite of doing. Mediocrity, in other words, is about not trying. The reason is achingly simple, and I know you've heard it a thousand times before: what doesn't kill you makes you stronger.
