I don't call them sacrifices. I call them exchanges.

I think about my goals. There were a lot of times in gymnastics when I really didn't want to go in and train, but you can't make it to the Olympics if you don't train!

When it comes to gymnastics, you can be 30 points ahead going into that competition, but on that day, it's all about luck. It's about who has a good day, who stays healthy, it's how happy the judges are that day, there are so many different factors.

My coach, Liang Chow, had one rule while I was training for the 2008 Olympics: no skiing. I could do anything I wanted outside the gym, he said, except ski.

I was always trying to be leaner and thinner to fit the standard and the mold.

To finish off this whole Olympics by finally getting the gold medal, it's the best feeling in the world.

Gymnastics taught me everything - life lessons, responsibility and discipline and respect.
