I don’t make “to do” lists anymore. I find I accomplish more if I make a “done” list. It’s very satisfying to add something you’ve got done to the list each time. I’ve been known to push myself just so I can have another “done” thing!
I still make shopping lists…and almost always manage to leave them home when I go out. Anything really important gets written on a Post-It note and stuck where I will have to move it (and therefore see it).
