I do catch myself driving around singing tunes, but I don't know if it's necessarily show tunes.

For so long I wanted to win the gold medal.Then I won. I had to figure out what was the new motivation to take myself to that place again.

If I look what sport has done in my life, I don't think there's any doubt that sport can change lives.

I was blessed with certain gifts and talents and God gave them to me to be the best person I can be and to have a positive impact on other people.

Breaking the world record has always been in the works. I just need the right conditions and I can make it.

I've been telling people I'm in the best shape of my life, I've been training unbelievably hard.

How many times do you take yourself to the brink of complete collapse? It's not a real fun place to go.
