With discipline, belief, and the right knowledge, we become the best we can be.

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.

You think I was born rich? I've worked really hard. You have no idea.

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

I’m a martial artist, and I don’t train because I have a fight; I train because it’s my lifestyle, and I’ll train every day if I’m not hurt.

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.

Dana White came out very often in public saying I'm this and that; I'm sure it's also to play with my ego, to make me, for example, come out of retirement and say 'Oh ok, I'll fight for peanuts.' No, I'm not like that. I know the game.
