Baby, I am!
I have paper & pen ~ and therefore notes ~ in my car, beside my bed, in the kitchen, by my desks (at home & work).
I even take a pen to the bathroom with me (at home & work), because you just never know when a thought will strike you!
Maybe not so oddly enough, all of my friends are like this, too.
We have a lot to get done, and do not want to miss out on anything. We feel a sense of accomplishment when the items/activities are crossed off the list, and even more so when the list is complete!
Sure, it is easy to make fun of us "Note-aholics" if you are not one, but you gotta notice how much we get done!
