I've been using GTD for around 2.5 years now and like to think I'm okay at it.
I've developed a habit over that time of always thinking of the next action for a project if I finish the last action and writing it down either in Notepad (Palm), Outlook, Keysuite Tasks (Palm) or a note in the intray.
Also with time I´ve also seemed to have stopped writing a complete project list. Those on the list tend to be the sort of project that are slow burning move forward irregularly and therefore are more easily forgotten. Many projects never make it to the list. They start as an action and then just carry on with subsequent actions on the action list. I seem to have got pretty good at predicting when I need to have that "stake in the ground" as DA calls it and when I don't.
I´m not saying I never make a mistake and forget to write the next action, or fail to remember a current project but it happens rarely and the extra work in keeping a complete project list seems a lot compared to what I gain from it.
Is this heresy? It´s ironic because in the past the project list has been the thing I most raved about. Now it seems not so necessary to me. Has anyone had a similar experience using GTD?
