As Aristotle wrote a long, long time ago, and I'm paraphrasing here, the goal is to avoid mediocrity by being prepared to try something and either failing miserably or triumphing grandly. Mediocrity is not about failing, and it's the opposite of doing. Mediocrity, in other words, is about not trying. The reason is achingly simple, and I know you've heard it a thousand times before: what doesn't kill you makes you stronger.

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.

Fights aren't won in the octagon, they're won in the months leading up to them, in a near-empty gym, in the lost hours of a day, whether I feel like it or not.

Fighting is about knowledge, knowledge is a very important part of it.

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

Train smart at all times and do your best to avoid injury. Training smart is more important than training hard.
