I love Post It notes. Especially the 3-inch square ones. They’re the best way I know to keep lists … short lists that is. The best kind of list has no more than 5 things on it, preferrably less. They’re do-able, specific, and not terribly intimidating. If it fits on a Post It, you can get it done today, right? I like to think so. Having a list where everything gets crossed of is rather important to my sanity, and the shorter the list the better chance I have. Try it sometime :).
