Projects have end results.
Action items are doable visualizable simple tasks.
Often, an action item is just a 'placeholder' or 'bookmark' -- the initial action that will kickoff a series of actions that will get you a few steps closer towards completing a 2-month project.
That initial action may be doable, it may be simple -- but, because it is so far removed from any desirable end result, it is not inspiring.
The end result of the project is often too far off and too big to have any magnetic affect on me. The end result of my day, on the other hand, is close enough to draw me -- but it isn't defined.
I am thinking that if I captured something like, "What needs to be accomplished to make me consider today a success", that might be a magnetic motivator.
But it isn't an action item, and I don't think it is a project. What is it, does it have a place in GTD, and what is that place?
