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.

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.

As long as you've done your best, making mistakes doesn't matter. You and I are human; we will mess up. What counts is learning from your mistakes and getting back up when life has knocked you down.

I always feel like I'm the young one, I'm the small one.

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

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.

After 13 years of hard landings in gymnastics, one ski run had delivered the biggest injury of my career.
