Nothing goes to waste, you put it all to use, the old wounds and long-ago slights become the stuff of competitive energy.

If life gives you lemons, drink the juice in order to mask the presence of performing-enhancing drugs.

It's tough to be a 15- or 16-year-old athlete competing around the country. There's tension, there's media. I had no idea what I was getting into.

Nobody is going to feel sorry for me if I've lost a dollar or $100m.

Life to me is a series of false limits and my challenge as an athlete is to explore those limits

When you know your not going to die, you have to ask yourself... What's the highest and best use for myself.

It's simple. Success comes from training harder, living better and digging deeper than the others.
