Training with Bela and Marta Karolyi took the joy out of the Olympics for me. I look back and feel there was a lot of verbal and physical abuse. For years, I felt it was my problem.

As a competitive gymnast, my life has always been filled with challenges that would ultimately define my future. From day one, I was taught to be prepared at all costs.

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

I had this sister that was born who was given up for adoption, and I never knew it.

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.

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.
