I like lists. Lists for grocery shopping. Lists for Christmas shopping. Lists of the knitting/other crafting projects I have on the go. Lists of home improvement things I want to do. Lists of what I need to get done at work. The list could go on (groan).
Partly, I need the lists so that I can keep everything straight and I don't forget the cat food, or that the dishwasher has clean dishes in it. Partly, I keep lists so that I am motivated to do things (at least in theory - "Paint the kitchen" has been on my home improvement list for about a year and a half now). My third reason for list-keeping is the satisfaction I get when I can cross something off the list. It's like saying "Look! See what I accomplished? Somebody praise me already."
Sometimes (especially at work) I will add something to my daily list that I have already done, just to have the satisfaction of having another item on my crossed-off list.
I am sincerely hoping that I am not the only person in the world who does this....
