A businessman needs a laptop. Athletes need massages and the right diet.

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

Running was like the friend that never left. It was just always there.

Stepping on that line for me, it will be about facing my fears.

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.

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

It took Dan Jansen, the speed skater, four Olympics to win a medal-a gold one at that!-but he never gave up. I won't, either.
