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
Spatial expectations Loya, who served seven years in prison for multiple bank heists before becoming a writer, explained to me that it was during the getaway that he often had the best chance of thwarting people’s spatial expectations. In his case, this meant that what he did immediately after leaving the bank was often the most important decision of all. Geoff Manaugh, A Burglar's Guide to the City Bandits
