Gymnastics is so complex.

Something my mom taught me when I was little is that everything happens for a reason. Retiring was scary and it was tough to give up gymnastics, but so many great opportunities have come from it that I never expected. And those wouldn't have happened had I not accepted my injury as a way to try something new.

It's been strange and weird watching the other girls at the U.S. Olympic trials just because I was training to be out there myself.

When I was younger, my coach, Liang Chow, made all the decisions. I would go to the gym for practice, do exactly what Chow told me to do, go home, come back and start all over again. If Chow told me to do 50 squat jumps, I did 50 squat jumps.

When it comes to gymnastics, you can be 30 points ahead going into that competition, but on that day, it's all about luck. It's about who has a good day, who stays healthy, it's how happy the judges are that day, there are so many different factors.

I set my phone with motivational quotes to go off on random days and times. Like, 'You're stronger than you think you are.' I'll forget about it, then one will pop up and it'll give me a little boost.

I've never had a teammate competing with me my whole life.
