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.

I want to use every second of my life, every time that I have in my life, to make me a better fighter. That's why I'm a martial artist. For me, it's more than a job - it's a way of living

I will never take the fact that I am Welterweight Champion for granted. I learnt my mistake in the past. No matter how great, no matter how people tell me how great I am, I'm always one mistake away from losing everything.

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.

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.

When I train, I love to take time off and fly to the Natural History Museum or an exhibition. I just love that. When you know your past, it will help you with your future… That’s why most of my friends are not fighters. Most of my friends are nerds like me. That’s why I have a hard time finding a girlfriend. I need someone to talk science with. I’m married to my work right now. But you never know. One day I could wake up and just do something different. Life is so unpredictable.

I try to protect my loved ones, the people I share my life with, because they don't have a public life like me. I want to keep their lives private out of respect for them.
