How much of this planning model do you really need..? [A]s much as you need to get the project off your mind. — David Allen

[Y]ou must have a clear picture in your mind of what success would look, sound, and feel like.

It's great to clear your psychic decks so you can go into the weekend ready for refreshment and recreation, with nothing on your mind.

The organizing system merely provides placeholders for all your oprn loops and options so your mind can... make the necessary intuitive, moment-to-moment strategic decisions.
