It’s generally accepted we need around 8 hours of sleep daily. But who says we should sleep at night or all in one chunk. Varying your sleep cycle can help you find more time in your day and put more creativity in your work.
Look at it this way: The majority of your distractions occur between 9am and 9pm. Why? That’s when the majority of your time zone is awake. By working a bit later or getting up a bit earlier, you get more uninterrupted hours.
You might even consider sleeping during the day and working at night. Chances are your job/wife/kids wouldn’t prefer that. So why not take a short nap during the day and wake up for an hour or so at 2am and work?
Some people even go as far as practicing polyphasic sleep. You’ve probably heard of this from the show Seinfeld, but some people actually don’t sleep 8 hours a day. Instead, they take short naps. The Uberman Sleep Cycle, for instance, is six 30-minute naps taken at regular intervals throughout the day. That’s only 3 hours/day!
I’m not espousing polyphasic sleep, but don’t feel bound to the traditional concepts of sleep. Experiment a bit. Change up your sleeping patterns and see what that does for your creativity.
