Okay -- after a lot of study and reading of great posts here and looking closely at my current system of categorizing next actions by roles, I have decided to go back and try the more standard context categories again.
I had a epiphany if you will on this and something I think Scott Lewis had mentioned in one of his posts. I went on some errands and found out that I missed some things because all of my errand items were not on an @errands list -- they were divided amongst my many roles. SO, I will redo my context lists as follows: @calls, @errands, @computer, @internet, @office, etc.
I'll keep everyone posted as to my progress! Oh my.
