Perspective from someone who has a day job and does his own project when not at work: My routine works best when I wake up at normal work hours ~8am and go to work after coffee via subway. At the office I take a 15 minute nap on a bean bag chair in the evening, drink a cup of coffee, then go to the gym. When I get home I'm awake and feel productive most of the time so I can attend to my website. So if I choose to be productive anywhere between 10am and 2am, it's usually not difficult. If I was working full-time on a startup without a day job, I would assume I would still work best at night like I did in college rather than the 4am-7am early morning hours.
