I'm using a palm pilot to track my projects list and the next action lists.
When your lists get really long, does anyone have smart ways of keeping track of what next action has been assigned to a project?
At the moment, I'm doing this:
I number the projects with a code: P1, P2, P3 and so on.
Then, when I assign an action, eg, "Call Fred" in the "Phonecalls" list, I give it the relevant project number, eg "P4 Call Fred."
That way, when it's weekly review time, I can do a Ctrl-F and type in "P1" to see both the project and the next action if it's not been done. I can decide if I'm happy with that next action or if I need to change/add it.
That works ok as a system - but does anyone have any better approaches that they use when apply GTD in this way?
