I am a list-maker.
At the moment I have countless lists going. I have an Access database of all the movies I've ever seen complete with the year they came out, lead actor and/or actress and director.
I have another Access database of our guest list for the wedding. An Excel spreadsheet for the wedding with several pages - budget, wedding party, locations, etc., a wedding planning book/filer with more lists and magazine cut-outs, and still another blank book for making random wedding lists off the top of my head that I don't think are ready to commit to the computer.
Over the years I have started several databases to catalog the books and cds I own, having to re-start them from time to time as I have had new computers.
In order to accomplish anything on my days off I have to make a list of things I want to get done. If I don't, I will wake up in the morning and honestly have a blank mind as to what to do for the day.
Awhile back I made a list of things I wanted to accomplish in my life. I've actually crossed many of them off, and such progress caused me to add to it.
I have to have a grocery list, or I will go to the store for lasagna noodles and come out with cheese, veggies, ice cream, toilet paper, milk, bread, garlic, veggie crumbles and no noodles.
I have a blank book for budgets, which I've also found easiest to keep my checkbook register in as well.
I have lists of all the states I've been in and all the states I have yet to visit. Last night I actually wondered if it would be possible to list all the people I know, personally, as aquaintences, whatever - just because it would be interesting.
When I'm at work I'll make lists of things I want to make sure get done before the end of the shift. I make lists from other lists. A list of books people have requested that we carry, a list of dogs people would like us to get, a list of things to go back later and make more lists from!
If I go on a trip, I start about a month before hand making a list of what I need to take. On two occasions I have decided to skip the list and pack "on the fly" and have forgotten underwear, socks, toothbrush (although I remembered the toothpaste!) and other various necessities.
I even have a list saved on my desktop of things to blog about.
