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.

The key to effective visualization is to create the most detailed, clear and vivid a picture to focus on as possible. The more vivid the visualization, the more likely, and quickly, you are to begin attracting the things that help you achieve what you want to get done.

There is a difference between a fighter and a martial artist. A fighter is training for a purpose: He has a fight. I’m a martial artist. I don’t train for a fight. I train for myself. I’m training all the time. My goal is perfection. But I will never reach perfection.

You don’t get better on the days when you feel like going. You get better on the days when you don’t want to go, but you go anyway. If you can overcome the negative energy coming from your tired body or unmotivated mind, you will grow and become better.

Growth is a long term game, and the crappy days are more important.
