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.

My fear delivered one of the great lessons of my life: That someone without fear can’t push himself. He can’t get better. He can’t transform negatives into positives. He can’t open his world to creativity and invention, or even progress.

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.

I am very honored and excited to be part of UFC 100, it's going to be the hardest challenge of my career so far and it's going to be pretty tough, I can't wait.

My mentality is like a Samurai: They used to every day work on their technique to make themselves almost perfect. Because perfection is impossible, but every day, you get closer to perfection.

In fighting, in evolution, in life, efficiency is the key.

I'm an athlete, my job is not negotiating, it's not my field of expertise. I'm an emotional guy - it's normal, a lot of athletes are, and we're very susceptible to get our ego cut because of that.
