In keeping with “Keep it Simple” and to align with GTD, I have three sections in my primary notebook:
Capture is the catch-all for collecting things – ideas, clippings, emails and so forth. The section holds these until they can be properly organized. Some items are immediately sent to trash, otherwise they get classified, prioritized and moved to Organize.
This is the clean room. Only items currently being worked belong here. This helps prevent distraction.
This is the final resting place of all notes. If they have been prioritized, the tag search picks them up for future work. If all actions are complete, the note settles into the bottom of the Organize section where it can be referenced in the future.
