I just finished reading Swimming Studies by Leanne Shapton. I really recommend it!
“Water is elemental, it’s what we’re made of. what we can’t live within or without. Trying to define what swimming means to me is like looking at a shell sitting in a few feet of clear, still water. There it is, in sharp focus, but once I reach for it, breaking the surface, the ripples refract the shell. It becomes five shells, twenty-five shells, some smaller, some larger, and I blindly feel for what I saw perfectly before trying to grasp it.”
