I love all sports but the ones I do are : mountain bike, snowboard, surf, and dirt bike.
My training has changed a lot over the years. Especially what I do out of the water. I believe in mixing things up and enjoying what your doing so that it never gets boring or feels like work. I try and do a lot of cross training like mountain biking, etc.
I was that 14 year old that was pretty oblivious to how big the Olympics were. That definetly helped me stay calm and just have fun.
