Opting for gold shoes could have been considered downright cocky, but I was confident and never doubted my ability to deliver gold medals to match my shimmering footwear.

When you're gone I can go running though the house screaming and no one will ever hear me.

The only one who can beat me is me.

There's a complete difference between training for a specific event and goal and just training.

As strong as my legs are, it is my mind that has made me a champion.

The mind is absolutely instrumental in achieving results, even for athletes. Sports psychology is a very small part, but it's extremely important when you're winning and losing races by hundredths and even thousandths of a second.

I've had to learn that not everybody does things my way. But I do expect the absolute best of everyone around me, and I'm disappointed when people don't expect that of themselves.
