It wasn't hard going to the gym, as long as he went as soon as he woke up, before he had time to think about not going. Those morning workouts made him feel like he was starting his day like a pinball, with a giant shot of momentum. The feeling sometimes didn’t wear off until six or seven at night (when it was usually overtaken by the feeling that he was just bouncing haplessly from one situation to the next without any real purpose or direction).
