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.

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

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.

People put too much emphasis on looks.

I still can't believe I'm an Olympic athlete.

I had a constant fear, a constant little doubt in my mind: 'OK, I'm getting ready to do my standing back full on beam and I might re-tear my ACL.'

Stay strong. Stand up. Have a voice.
