I've been on a tweeting mission.

I used to have this lucky rock and I used to always have to rub it three times before I competed.

Gymnastics does take great focus and concentration. What I do is look to my coach. He keeps me focused. And I meditate to get myself confident before the competition floor. That helps keep me focused, too.

The most important thing is to believe in yourself and know that you can do it.

Don't be shy. Go for it and ask your crush out.

Never quit. Never give up.

The other girls [in team] have experience. They've been competing on a lot of international world-class stages. They knew what to expect and what to do and what not to do. Me and Aly [Raisman] just gave them advice on the media side. We said, it's gonna be crazy. It's the Olympics. But it's gonna be fun!
