Just read someone's 100 Things list. What got me was, "Twenty-five. I have notebooks full of useless html that I haven't used yet."
See what I mean? We keep text for future use.
Oh, and "Thirty-two. I use post-it notes all the time. My wall beside my computer has about 10-15 post-its up there right now." People are strangely, almost fetishistically, aware of their habits of mediation.
