I was always known as that stocky, muscular, powerful, short, athlete. People always wondered if I was on steroids, and it was because I wasn't that long and lean, flexible, artistic gymnast. It didn't affect me too much but it got to the point where I tried to be that long and lean gymnast, and it just wasn't possible.

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.

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.

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

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.'

Don't force anything. Find what you love and stick with it.

Everything for me started with my love of the sport. In society we're losing the fun with kids and pushing success on them too hard. Success comes from fun.
