I have a hybrid solution. My to-do list is a Word document called Notes.doc. The document is a set of headings, one per project/product I'm on. Beneath the headings, items are bulleted lists, in order by priority. As I complete items, I mark them off a hard copy. I write immediate concerns, new items, and reminders on sticky notes and in the margins of the hard copy. Whenever I have a spare 10 minutes or so (once or twice a week), I consolidate the sticky notes and margin notes into Notes.doc. This is also a good time to reorder the items as priorities shift. It's not terribly high tech or efficient, but it works for me. In this case, low tech has the advantage of also being low maintenance. I think that's the key. For a personal information scheme to be worthwhile, it has to be one that you will use. If I have to spend a lot of time doing data entry in the scheme, it's not going to work. The Word document I use is very simply formatted. The handwritten updates are simple and quick. Consolidating the document every few days is an opportunity to take a quick step back and look at the broader picture.
