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

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.'

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 set my phone with motivational quotes to go off on random days and times. Like, 'You're stronger than you think you are.' I'll forget about it, then one will pop up and it'll give me a little boost.

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

I have a chaperone everywhere I go - my mom.
