I know that this is little art and little science, but I would like to know from people who are making the system work for themselves, how they decide what number of n/as is right. for various contexts.
Viewing GTD as a task managing system (per Kwems in another thread), it occurred to me that that I still am not making good use of the n/a lists because I have ridculously too many actions on these lists.
Of course, I should have known this just by reading the book, etc., but I didn't get it. All of my working life, I have coped by commititng to more than any single person could do, either in scope or the number of projects, and then feeling that doing 1/3 to a 1/2 was more than fulfilling my obligations to myself and others. So, it can readily be seen how my coping style lead me to make the mistake of too many n/as.
So what do those who are feeling in control and ready for anything use as a guide?
I do understand that each n/as should be transient, that is done, then gone and then replaced by the next one.
But at the points when the system is "refreshed" (weekly review), how does one decide when enough is enough?
