“Look, when I started studying Olympians, I thought, ‘What kind of oddball gets up every day at four in the morning to go to swimming practice?’ I thought, ‘These must be extraordinary people to do that sort of thing.’ But the thing is, when you go to a place where basically everybody you know is getting up at four in the morning to go to practice, that’s just what you do. It’s no big deal. It becomes a habit.”
