I make lists because I am so forgetful. I have so much to do during the day, if I did not make a list half of it would not get done. Hopefully this does make me anal.
I also make lists, especially if I have a number of errands to run, I'll make a list and put the different places I have to go to in order for best possible distance and time sequence... but I usually forget and leave the list at home.
I bought one of those self help books on how to improve my memory...where the heck did I leave that thing? I haven't seen it for days. I know I never took out of the house..........I couldn't have left it in the car....hmmmmm.......
I make lists too, because I can only remember so many things at once. I think it's quite normal and really a sensible way to keep track of stuff. Don't over think it if it works for you.
