I have been using GTD for some time now. I have seen many variants of GTD through this forum. Perhaps this is what makes this system so usable -- one can adapt it to fit his/her lifestyle/work environment!
Now, one problem that I STILL have problems with is categorizing all of my next actions by context -- @calls, @computer, etc. I still find it most efficient for me if I use my life role categories -- @scientist, @mentor, @Family, etc. I have a computer wherever I am working -- in my office, my home office, my laptop on trips.
I guess I am asking for comments again on this. I know this is categorizing next actions at more of the 20,000 feet level, but dumbing it down to @computer, @calls just doesn't seem to work that well for me.
