This separates the women from the girls
I think your problem is probably something that marks the difference between "functional GTD" and possibly giving up entirely. I've had similar problems, and here's what helped me:
Pare down the number of lists that you have. I think jumping around on too many lists just adds to your stress.
Have ONLY the next actions that you plan to complete in a period of time before your next weekly review on the list. Dump EVERYTHING else into Someday/Maybe or perhaps create a list called "pending". Don't even look at that list until your next weekly review. KEY to this is that you DO a weekly review, or stuff will get lost.
Make a list at the end of each day or the very beginning of your workday that contains ONLY the items you plan to work on that day. This works for some people, and not for others. Don't add to this list, though....just make sure you are taking items from your Next Actions lists.
Get busy on implementing GTD at home. If you have any life at all, this is a LIFESAVER. You are a whole person, not just an employee! This will greatly reduce your feeling of stress...and that carries over into work.
Good luck...and keep us posted!
Consolidating context lists
One thing that has helped me is doing away with so many contexts. I also was scanning all of the standard context lists -- @computer, @Anywhere, @Office, etc. and it was always difficult to choose. I since realized that I almost always have all of these tools in my office and laptop, and so I have pared down my contexts to @Actions-Work, @Calls, @Errands, and @Home. This makes it simpler, at least for me, to scan through my main list -- @Actions-Work than going across several contexts. I also use the Someday/Maybe list very strongly and only have next actions that I want to consider doing or must do this week on my lists -- everything else goes on SOmeday/Maybe and I revisit this during my weekly review.
Comments on this approach?
