Through everything I've gone through- and I've been everywhere, at the top of the world, in jail, hung over drunk - I never gave up my dream of winning a gold medal in the Olympics.

As a young child, I was never a crier. I never cried to get my way, or even when I was in pain.

Try everything, because you're never sure what you're going to be great at.

It's important for me to think I'm mixed-race.

When first starting to work with someone you try to get them in the same mindset that you were in when you were successful, and I realized the best thing you can ever do is realize that they are not you. They have a different persona and mindset, and you have to figure out what works best within your communication with that athlete.

You need to become more than one type of athlete. You have to be a sprinter, a weight man and a distance guy all in one.

It really means a lot that I won the gold medal - but I woke up the next morning expecting to feel different. I felt the same.
