Sometimes its not what's idealistic that sets your schedule, there's just things in life that happens that won't allow you to do what you feel like doing at times.
I know for me, time spent sleeping away is time lost doing other important things that MUST be done TODAY, not tommorow. Not very often do I let the clock set my pace of work, I work when I work when I work. Sleeping is the least of my priorities. Sure I'd like to hit the sack when I'm tired, but that's just not always possible. I'm a procrastinator as well, so that doesn't really make things any better 😛
What can I say, I'm a full blown insomniac.
