It's not how you start, but it's how you finish.

Nothing is impossible. With so many people saying it couldn't be done, all it takes is an imagination.

This is my 20th year in the sport. I've known swimming and that's it. I don't want to swim past age 30; if I continue after this Olympics, and come back in 2016, I'll be 31. I'm looking forward to being able to see the other side of the fence.

Perseverance, determination, commitment, and courage-those things are real. The desire for redemption drives you.

Every day after I wake up, I think, 'Wait... this can't be real; I'm still going to wake up.'

The problem with heart disease is the first symptom is often fatal.

My goal is one Olympic gold medal. Not many people in this world can say, 'I'm an Olympic gold medalist.'
