The Olympics is a once-in-a-lifetime thing. I was lucky enough to go twice, but most people only get one chance. And in judo you can train your whole life and it’ll come down to a split second: You can lose everything or win anything.

It's your purpose to leave the world better than how you found it.

I don't shy away from any questions. I'm not scared of any question. I'll give you an answer. A lot of people are scared of having actual opinions out there. People are so scared of criticism I'm not scared of people disliking me.

Reality TV is set up to make people entertaining. A good person with values and principles is not good television.

I am vulnerable; that's why I fight.

If I could have had everything exactly the way I wanted, this is how I would have written it down. Win all my fights in the first round, then go to the UFC and headline a show, and have it as a pay-per-view and at home. People's dreams don't come true like that.

At home, I watch fights and documentaries - that's it. If it's not about the birth and death of stars, 'Frozen Planet,' or someone getting punched in the face, I'm probably not watching it.
