At the 2008 Olympic Games in Beijing, she won a bronze medal, becoming the first American woman to win a medal since judo's inclusion in the Olympics.

If there's chaos, it's good. And I need to put myself in situations where people are going to doubt me because I don't ever want to be in that lose lose situation where if you win, it's like, "Oh, of course you won," and if you lose, it's the end of the world. I want everyone to tell me that I can't do it because that motivates me more than anything.
