The absent-minded professor There are three variants of procrastination, depending on what you do instead of working on something: you could work on (a) nothing, (b) something less important, or (c) something more important. That last type, I'd argue, is good procrastination.

His mind is absent from the everyday world because it's hard at work in another. Paul Graham, Good and bad procrastination procrastinationproductivity
