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
Maps and observation Maps are useful only when they are used in combination with observation. Never try to design a site by just looking at a map, even if it is thoroughly detailed with contour lines, vegetation, erosion gullies, and so on marked in. Maps are never representative of the complex reality of nature. Remember, "The map is not the territory." Bill Mollison, Introduction to Permaculture BlueprintsGuided by image mapsrealityarchitecture
