I'm sorry you're having such problems! I'd love to help.
Okay, interesting. What information would you need at hand to be able to make that decision?But here is the problem-- I don't have enough information at hand to know if I should stay in the context and work on the one I just listed or select other n/as or if I should switch contexts in order to stay on the project or work on another.
Good! You're making those hard decisions. Those hard decisions will need to be made anyway.And, further complicating my decisions about selecting an n/a, if it is several days' time from when I entered it or several action steps away from the execution of the initial action, I have to think hard about the n/a because sometimes the n/a I have listed is wrong, because I did it already (from the list several actions back or intuitively), or when I created the n/a it seemed logical at that moment but it turns out it really isn't a next action and I don't realize it until I am part way through, or, even wrose, I am purseing an aspect I decided to defer or exclude but forgot I excluded it. The later genreally happens if I create an n/a right after completing one and don't have my project materials to refer to at the time.
That said, there's one thing I want to comment on: you write that sometimes your n/a is wrong because you did it already. Perhaps you're not using your NA lists that often?
I may be wrong, but this sounds similar to the oft-heard problem, "How do I choose a Next Action when there's no obvious best one?" To which the answer is, "Just pick one."But then I have a question come into my mind, "Should I stay in this context or change contexts?" I start to think that maybe I ought to check and see if there might be a good reasons to change contexts....
It sounds to me like you're second-guessing yourself. I suggest that you just stick with whatever context you're in. The external world will change contexts on you often enough!
How up-to-date is your NA list?I have a problem with choosing the next action because my list by context is so separated from the milieu of my life and from the other projects.
