The mantra I used was 'find a way.'

Swimming is probably the ultimate of burnout sports.

Just getting in the pool for seven straight hours is unbearable to me.... It's grueling. There's nothing physically pleasurable about it. If you're doing a hard workout, you're throwing up in the gutter. At night you cling to your pillow and just hope that your body revives before you have to go back and do it again.

From age eleven to age sixteen I lived a spartan life without the usual adolescent uncertainty. I wanted to be the best swimmer in the world, and there was nothing else.

I want to see all the countries in the world and learn all the languages. I want to have thousands of friends and I want all my friends to be different. I want to play six instruments. I want to be the best in the world at two things. I want to be a great athlete and I want to be a great surgeon. I need to practice very hard every day. I need to sleep as little as possible. I need to read at least one major book every week. And I need to remember that my seventy years are going to go by too quickly.

But for each of us, isn't life about determining your own finish line?

When I walk up on that shore in Florida, I want millions of those AARP sisters and brothers to look at me and say, 'I'm going to go write that novel I thought it was too late to do. I'm going to go work in Africa on that farm that those people need help at. I'm going to adopt a child. It's not too late, I can still live my dreams.'
