Beginning with Doom, he had decided to adjust his biological clock to accommodate a more monkish and solitary work schedule, free from Romero’s screams, the reporters’ calls, and the mounting distractions of everyday life. He began by pushing himself to stay up one hour later every evening and then coming in one hour later the next day. By early 1995, he had arrived at his ideal schedule: coming in to work at around 4:00 p.m. and leaving at 4:00 a.m. He would need all the concentration he could muster for Quake.
