I've been barefoot most of my life: either flip flops or barefoot on the pool deck. Although you'd think that would make me a good candidate for barefoot running, that doesn't work with me.

I think some parents fall into a trap, teaching their kids that everything is always perfect and everyone is always a winner.

When I was younger, I would eat everything.

Swimming is great because there are levels of goals. First, when I was four, it was making it to the other end and overcoming the fear of standing up in front of everybody at a swim meet because I was such a shy kid.

The things you learn from sports - setting goals, being part of a team, confidence - that's invaluable. It's not about trophies and ribbons. It's about being on time for practice, accepting challenges and being fearful of the elements.

The first mile is mental. The rest are all heart.

Don't just tell your kids to be active and to get outside and play. Lead by example.
