Success is always an easier motivator, because you want more of it. But I've also been motivated by failure. Had I medaled in London, I don't think I would be one of the few that have gone to a Summer and Winter. I would have been content with that medal. Instead, I used that failure to go to the Winter Olympics. I always tell people that failure can be one of your biggest motivators if you just have an attitude adjustment about it.

As a young girl, I just wanted to have fun and compete. There were no goals of becoming an Olympic athlete. I wanted to hang out with my friends. I wanted to do something fun, and that's what I did

A failure isn't a failure if it prepares you for success tomorrow.

There's always a point where you get knocked down. But I draw on what I've learned on the track: If you work hard, things will work out.

Sometimes bad things are going to happen in your life, and those things can make you stronger if you just learn how to get over them.

Deep squats work so many muscles in your body. Once a week, I do three sets of six, or eight of the free-bar ones, which can help out your balance and work more muscles than doing them on the machine.

I'm inspired by failure. The process of defeat – picking yourself back up again is the hardest thing in the world.
