To have any doubt in your body is the biggest weakness an athlete can have. There are times when I physically can't get myself to go for a skill because I'm thinking, 'My knee hurts really bad.'

Retiring was scary and it was tough to give up gymnastics, but so many great opportunities have come from it that I never expected.

Gymnastics has made me strong. I feel like it broke me down to my lowest point, but at the same time, it has given me the greatest strength anyone could ask for.
