I'm optimistic. GTD has served me well since my original post. There have been times when I've let old, bad habits creep in of course. Like so many others, doing the weekly review seems to be a blind spot for me sometimes. But I have developed a reputation around the office of being "the guy who is very organized" and perhaps even "most able to roll with the punches." The 43 folders on my desk have led to many "What the hell is that?" conversations.
I probably won't make the move to the new job officially for a month or two, and in the meantime I'll be using GTD to help with the transition. Lots of capturing and processing of ideas and things to do with the new job, plus lots of processing and NAs for tasks in the current position that either need to be wrapped up or tidied up for a smooth transition to my successor.
Now that this thread his simmered for a couple of years, any new thoughts or follow-up from others in your experience with a "clean slate" GTD implementation?
