It's really impossible for athletes to grow up. On the one hand, you're a child, still playing a game. But on the other hand, you're a superhuman hero that everyone dreams of being. No wonder we have such a hard time understanding who we are.
Prepare yourself for the world, as the athletes used to do for their exercise; oil your mind and your manners, to give them the necessary suppleness and flexibility; strength alone will not do.
Athletes have studied how to leap and how to survive the leap some of the time and return to the ground. They don't always do it well. But they are our philosophers of actual moments and the body and soul in them, and of our maneuvers in our emergencies and longings.
