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 had a constant fear, a constant little doubt in my mind: 'OK, I'm getting ready to do my standing back full on beam and I might re-tear my ACL.'

I don't want to be all power and muscle.

In 2008 I didn't take it all in enough. I was so wrapped up in just the competition that I missed what was going on around me. If I am given that opportunity again to go to the Olympics and be an athlete I want to take it all in because I feel like this is my last shot and I want to feel the team spirit. I want to really live and breathe the USA.

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

That's the drama of our sport. Our margin of error is so small that anything can happen.

I fell in love with running, and I finally have time to do it now.
