Cranking Widgets Blog has a wonderful post, A Roadmap to Spectacular GTD Failure, that, as he puts it, “if you want GTD to over-promise and under-deliver, follow these simple steps…”
I think my favorite one is:
Make sure your filing system consists of unholy amounts of papers and crap strewn around your entire physical life – My office is too full of stuff to make room for a filing cabinet! I’ve had this “unorthodox” filing system for years and it’s only let me down… well, a couple of times. But who has the time to organize when you have as much stuff as I do!
I try to practice GTD, but I have been allowing too many distractions to come in, I have let my email become my filing cabinet, and I have not done a review.
