I do my best stuff midmorning and superlate at night, from 1 to 5 in the morning. Some people don't need sleep. I actually do need sleep. I just sleep all the time. I'll catch naps in the afternoon, or I'll take a 20-minute snooze in the office - just all the time. Our business is 24 hours. Our guys in Europe come online at midnight.
