When I was younger, my coach, Liang Chow, made all the decisions. I would go to the gym for practice, do exactly what Chow told me to do, go home, come back and start all over again. If Chow told me to do 50 squat jumps, I did 50 squat jumps.

I've never had a teammate competing with me my whole life.

There's always a chance. Anything can happen.

I told myself after 2008 that I was done for good. But they say you can't keep a gymnast away from her sport.

I don't think I've ever not gotten nervous. When you work so hard for one special day or routine, you want to perform it better than you ever have. We always say at our gym, If you lose the nerves, you lose the sport.

I was at the Olympic Games winning medals and I still doubted my image. I doubted what I looked like. That's sad.

People put too much emphasis on looks.
