Well, I thought this post might result in a few replies....
Thanks to all that took the time to give me advice. Here is what I am doing. I still follow most of the GTD principles with the five phases, but have modified the doing part. I applaud those of you out there that not only can function well on continually scanning long next action lists each and every time you need to decide what next to do, but some of you thrive on it! I am just one of those people that likes to create a daily plan and try to follow it. I do like the closed list approach of Mark Forster, but do not practice it rigidly at all. Remember, folks, since many of you quoted what David Allen has said about daily to-do lists, here is what he said on page 40 of GTD about daily plans: "Having a working game plan as a reference point is always useful, but it must be able to be renegotiated at any moment". I do believe this, but I also see the power in creating a working daily and weekly plan as a template. I just function better this way versus simply scanning next action lists and choosing what to do by the seat of my pants.
So, I create a daily focus list of actions -- from my next actions list -- and work hard at getting these done. If something comes up that is very urgent and important, then of course I embrace this new work coming in -- the great flexibility of GTD.
My philosophy...my way of doing things.
Best to all,
