Many, many years ago (at least five), Finn Arne linked me to this essay on structured procrastination. I was struck by its good sense and wise suggestions. And I have been trying it out ever since. Not always with great success (unless you count knitting sweaters and reading books quite unrelated to my work -- not to mention keeping up to date on geek culture and a selection of television series -- as a form of achievement), but certainly with a bad conscience (which is second place when procrastination is concerned).
