Even being done with classes "officially" (papers turned in, finals completed), I am still running my life completely via my to-do lists. In fact, they almost seem busier than usual. The glorious feeling of freedom from homework was fleeting when my lists started filling up with normal "real life" issues.
I can't function without making a list. In fact, I end up making about three or four a day. I think there are four categories that are absolutely necessary: Sticky Notes, Notepads, Notebooks, & Mousepad Notepads.
I use sticky notes all the time. I stick them on the corner of my desktop with important things I can't forget, on the door with little reminders, and in my agenda with mini-lists.
Notepads for packing lists, favorite quotations, and talking points for telephone calls. I use these for more hodgepodge types of lists.
I always carry a notebook or two with me. I write down my homework in them. Little notebooks are also perfect for taking notes while I'm on the go! If I need to remember something, I just jot it down in my handy notebook.
My workload that I need to complete on my computer (or anything that I'll be working on on my desk) gets written down on my mousepad notepads. Generally they start off as a medium-length list, but by the end of the day the whole thing is covered in notes, doodles, reminders, and various marks.
Do you use to-do lists? What do you use to write them down?
