I am excited to have the opportunity to help provide the same swim instruction that I received as a child when I was enrolled in a water safety class at five-years-old.

My little son is already like me - my mom has always said I used to bounce off the wall and never stop talking or sit still. I'm starting to see that with him. I guess it's living proof he's part of me.

Other nights ... I visualize to the point that I know exactly what I want to do: dive, glide, stroke, flip, reach the wall, hit the split time to the hundredth, then swim back again for as many times as I need to finish the race.

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

Why is it such a big deal what I'm swimming?

If I bring back only one gold people are going to say it's a disappointment. But not too many of them own an Olympic gold medal so if I get one I'm going to be happy.

So many people along the way,whatever it is you aspire to do, will tell you it can't be done. But it all it takes is imagination. You dream. You plan. You reach. There will be obstacles. There will doubters. There will be mistakes. But with hard work, with belief, with confidence and trust in yourself and those around you, there no limits.
