I was 26 years old when I found out that I had a sister who I never knew existed.

I learned to take those experiences that were difficult in my life and in the adversity that I had overcome to use it for a positive change.

In my very first interview, at nine years old, I said I wanted to be an Olympic gold medalist. That was the first time I said it out loud in front of somebody other than my parents.

My parents enrolled me in a gymnastics class when I was three years old, and I just was drawn to gymnastics. I loved it. It was my playground, and I could run around and be free there.

It's human nature to be timid in the face of obstacles, but I have learned to believe that challenges are opportunities for genius to shine. In order to feel alive, we have to accomplish things that we once believed we could not.

Autographs and pictures do get a little old, but I don't mind if the people want it.
