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.

My approach to gymnastics in Beijing was heavily based on the amount of difficulty I could do.

I started taking gymnastic classes when I was 3 years old.

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.

Of course, when you're training your whole life to get to the Olympics, you train for gold.

When I was 3 my parents put me in gymnastics because I was a bundle of energy and they just didn't know what to do with me! They put me in a Tots class and I just fell in love with it.

I had surgery to repair the ACL in February 2010 and was back in the gym by June, but rushed things too quickly and ended up re-tearing my MCL in September.
