I know a few librarians that are as compulsive in their list making as I am. Just a hunch, but maybe something to do with librarians’ love of order makes us prone. Ta-da Lists are nice, but I really like having lists written down on notecards and in my Moleskine. If you’ve ever made a list of lists you’d like to make, you might enjoy reading about some styles of list making. I really like the idea of using check boxes (to retain legibility) in place of crossing items out, tho I doubt ticking a box is as satisfying.
