Injury taught me I need to learn how to face challenges.

Something my mom taught me when I was little is that everything happens for a reason. Retiring was scary and it was tough to give up gymnastics, but so many great opportunities have come from it that I never expected. And those wouldn't have happened had I not accepted my injury as a way to try something new.

Everybody sacrifices something in an attempt to reach what they think society wants.

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

It might have been easier to retire, to say my knee couldn't handle it and let that be that. At the same time, the prospect of not being able to compete in gymnastics anymore was heartbreaking.

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

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