I'm looking for ideas and strategies on how to reduce and simplify the work of maintaining GTD.
I'm not talking about eliminating any of the workflow stages. I understand that we have to capture, then process and organize, periodically review, and ultimately do our stuff. There's no getting around that. However, what can you do to streamline and simplify the stages? For example, eliminating inputs (cancelling newsletters, filtering inboxes, etc) can reduce capturing and processing time. The two-minute rule helps to reduce organizing and reviewing time. Not linking actions to projects (as I currently do in my system, but am not convinced is necessary) can reduce organizing time. Placing reminders into trusted automated systems can reduce reviewing time, as can cutting back on the frequency of reviews (e.g. David says he only thinks about his stuff once a week, or something to that effect).
Any good ideas out there for reducing and simplifying GTD to make it as efficient as possible to free up the maximum amount of time for doing?
