I am trying, again, to implement GTD. I have tried unsuccessfully a number of times. One thing I learned in past attempts is that I pay a lot more attention to my lists if I use a paper system for everything except my calender and contacts (smartphone) because I have to think more about them when I write them than I do when I type them. But I am running in to my same problem with contexts that I have had in the past.
I basically wear three different hats, or have three basic jobs, each with their own tasks and active projects. Except for meetings, I am in my office at all times and all work occurs there. All three of them require all tasks to basically be @office because they require a combination of phone or computer with hardcopy files that must remain in the office. I cannot perform tasks from "any phone" or "any computer", except for a few personal tasks. Because of this my @office context becomes huge with 95% of all tasks in the same context and it creates difficulty picking out an activity to perform because the list is so long.
I understand that the DA recommended contexts are just a starting point, but I can't seem to land contexts that work for me.
I'm looking for suggestions from others. I really want to make this work.
