Always pursue your dreams and work hard at it.

It’s OK to get butterfly in your stomach; the key is to learn how to make them fly in formation.

When I go on vacation I just like to do nothing - just hang out at the beach, go eat the best restaurants, and do nothing.

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.

I was a big fan of Jean-Claude Van-Damme growing up, and I always wanted to be a martial artist 'cause of him.

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.

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.
