For those familiar with Life Balance, I have been running my GTD system through LB using a generic "project template" which has floated around before.
It is something along these lines:
!Project : Successful outcome (context : anywhere)
---@Project Name (context: Projects - Active)
---?Project name needs next action defined (context: anywhere)
-------Next action #1
-------Next action #2
If you understand the logic of LB, you will know that as soon as all NA's of a given project are complete, I'll see the : "?Project name needs next action defined" show up in all my contexts, and it effectively becomes its own next action which says : "the next action in this projects is to define the next action".
This allows me to handle things on the fly, when I have time, or let it go when I don't, without the fear that it will be overlooked until next weekly review. It also shortens the time required to complete the Weekly Review.
