I'm still playing with my context lists. I know I'll get rid of @read/review, since that list is just growing. I read a lot, but somehow never what I put on that list (mental block perhaps?) Another context that I now love is @program, which I use primarily for 2 heavy programs. When in one of these programs, I often do a few things on my list. I got that idea here on the forum as a suggestion from someone (thank you again, someone) and it has saved me a lot of time. My contexts are as follows:
@pc (anything not to do with the heavy programs)
It is all a matter of fine-tuning regularly to customize it to your style. Since I joined this forum, I have made quite a few changes, most of which have worked and a very few not. Try to be rigid but flexible, which I think makes sense to GTDers.
