Hi -- I'm using a Jr Size Day-Timer for my GTD lists, specifically home/personal. I use Steve Bell's Excel GTD sheet for managing work lists.
I have mine set up just as David Allen describes in the tips and tools section of this site. Works great. In my Project section, the first page lists only ACTIVE PROJECTS, that is, stuff that is absorbing my attention for the next week-10 days. After that, are several Smday/Maybe pages. I date each entry.
[When you enter a project into your system, what else do you include? Intended outcome? A list of next actions? A mind map?]
I try to phrase the project such that it starts with an action verb, ie, "Install backup battery in UPS" or "Sell my old comic books"--this is the vision I'm working toward. When it's checked off, I know that project is done.
A separate tab is labeled PROJECT NOTES, per David's suggestions. Each page (pages) is dedicated to a single project. This is where I disgorge any next actions lurking in my brain. No particular order, just splat on the page. Pages aren't big enough for mindmaps, but that could be done. I don't have a page defined for all my someday/maybes, but I do for my active projects. It's a convenient net to catch any ideas related to any projects.
I keep my address info in my Psion -- more convenient and searchable. So I use the Address tabs to index reference material. "Sprint Conference Call" procedure is behind the S tab. "Gift ideas" list is behind the "GH" tab.
For the weekly review, I remove my action lists from the binder and update them as I review the Projects list. When they're updated, I insert them back into the D-T.
I like the tactile feeling of the D-T, seeing a whole page at one time, etc. I can also tell when I'm falling behind. On my @ lists, I write big so that only 3 or 4 tasks are on a page. I record the date on which a task is entered. When a task is done, I cross it out.
So, for example, on @CALLS, tasks are "8/31 Hotel for 9/19 reservation", "9/8 Dr. Taylor for appointment" , "9/10 Call Rani re party."
If i've crossed off the hotel and Rani, but I'm well into next week and Dr. Taylor hasn't been called, then I'm procrastinating that task, for some reason. Since I can only remove a page when all tasks are crossed off, it behooves me to get undone tasks renegotiated or completed.
Sorry for the long post. Hope it's helpful.
