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. That's the "absent-minded professor," who forgets to shave, or eat, or even perhaps look where he's going while he's thinking about some interesting question. His mind is absent from the everyday world because it's hard at work in another. Paul Graham, Good and bad procrastination procrastinationproductivity
A simple grain of sand "The desert will give you an understanding of the world; in fact, anything on the face of the earth will do that. You don't even have to understand the desert: all you have to do is contemplate a simple grain of sand, and you will see in it all the marvels of creation."
