I don't want to be an exception, because I was very outspoken about Performance Enhancing Drugs. It would be bad for my reputation if I would have an exemption [for doping test] - I don't want to have a free pass, I want to be like everybody else.

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

I've trained myself to fight an army, so one guy will not defeat me.

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.

I will never blame a fighter if he doesn't fight me because he takes care of his own interest first, and prioritize the interests of his family first, that's completely normal.

People often say, 'Ah, ultimate fighting is so violent,' but it's rooted in martial arts. Martial arts incarnate respect. You can't walk into a dojo and say to your sensei, 'Hey, salut tabarnac!' After every one of my fights I go and shake the hand of my opponent. I don't need to hate the other fighter to fight him well. It's a sport.

It's not the most powerful animal that survives. It's the most efficient.
