A Life Spent Swimming - Diana Nyad

Diana Nyad, famous for becoming the first person to swim without a shark cage from Cuba to Florida, has had two distinct swimming careers, separated by thirty years. In the first iteration, she sprinted in pools, and eventually set long distance records around Manhattan and from the Bahamas to Florida. She retired when she was thirty and says that she didn't swim another lap until she reached her 60's. When she resumed swimming, Nyad said the hardest parts weren't necessarily her long distance achievements, but having the discipline to get in the pool every day and train when nobody else was watching.
