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 still can't believe I'm an Olympic athlete.

Gymnastics has made me strong. I feel like it broke me down to my lowest point, but at the same time, it has given me the greatest strength anyone could ask for.

I pay attention to my diet to be a healthier gymnast, but I'm not obsessive over it.

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.

I have a lot of expectations and a lot of goals I want to fulfill, but the biggest dream is still to make the Olympic team for London.

As long as you've done your best, making mistakes doesn't matter. You and I are human; we will mess up. What counts is learning from your mistakes and getting back up when life has knocked you down.
