An upside to sleep deprivation?

I've spent the past week complaining about the effect sleep deprivation has on my mood, concentration ability, IQ, energy, and memory--but now I think there may be an upside. I am more creative. I suppose some of the aforementioned factors--fatigue, lack of focus and IQ--weaken my usual obsessive grip on What Needs to be Done and my rigid ideas about What Ought Not to be Done. As a result, I've been less productive and done things like eat French fries and take the elevator rather than the stairs--but I also find my mind expanding. I think more, rather than constantly seeking something on the agenda to do. New ideas are occurring to me. Suddenly I have half a dozen blog posts to write.
