It sounds funny, but the 2008 Olympics were something that just kind of happened, and I was lucky they came at a point when I was uninjured and well prepared. As a gymnast, you can't ask for much more.

To have any doubt in your body is the biggest weakness an athlete can have. There are times when I physically can't get myself to go for a skill because I'm thinking, 'My knee hurts really bad.'

It's nearly every country's tactic to keep their greatest competitors a secret.

I'm trying to stay as calm as possible and focus one day at a time, but when reality sets in, I feel everything: anxiety, excitement, nerves, pressure and joy.

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'm doing four hours of gymnastics training a day, six days a week and then an extra two to three hours in a fitness center as well.

Don't force anything. Find what you love and stick with it.
