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.

It sounds funny, but the 2008 Olympics were something that just kind of happened, and I was lucky they came at a point when I was uninjured and well prepared. As a gymnast, you can't ask for much more.

I get less and less sleep these days, so when I have any down time all I want to do is sleep!

I'm trying to stay as calm as possible and focus one day at a time, but when reality sets in, I feel everything: anxiety, excitement, nerves, pressure and joy.

I missed being considered an athlete and having that competitive drive, and missed having something to work for every day. I'd taken two and a half years away from the sport and was out of shape. I wanted to get back to where I was in 2008.

I pay attention to my diet to be a healthier gymnast, but I'm not obsessive over it.

Gymnastics taught me everything - life lessons, responsibility and discipline and respect.
