Retiring was scary and it was tough to give up gymnastics, but so many great opportunities have come from it that I never expected.

I get less and less sleep these days, so when I have any down time all I want to do is sleep!

People only see gymnastics on TV and in the Olympics at such an extreme. So it can be intimidating.

I missed being considered an athlete and having that competitive drive, and missed having something to work for every day. I'd taken two and a half years away from the sport and was out of shape. I wanted to get back to where I was in 2008.

In some ways the ACL tear was a blessing. I had hesitated to return to elite gymnastics after the 2008 Olympics. I told myself I had already accomplished so much, and the road was just going to get harder if I continued.

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.
