Seems like kind of a paradox. Too much to do, so you'll sleep when you're dead. But sleep deprivation will kill you, so you won't be able to finish all those things that are keeping you busy. :)
I always get eight hours of sleep ;) if a project exceeds my time availability, and cannot be automated, I delegate, even if it requires paying out of my pocket.
I'm notorious for taking on too many projects. Time to sleep when I'm dead.
