I've started late, I was 19 years old. I've trained with Victor Zilberman - he's a Russian-Jewish from Moldova. His son David who is coaching me represented Canada in the Olympic games. There were a lot of very good wrestlers there and they took me underneath their wing when I was young.

The truth is that I didn't start as a winner. When I was a kid, I was just another reject. I started at the bottom. I think all winners do.

I don't want things that I regret in life, and things that I have not done - and I don't want to at 80 years wake up, and tell myself: 'Oh I was on top of my shape and skills and I didn't do it.'

What happens when you accept and embrace your fear? Fear becomes your weapon.

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.

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.

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.
