Sometimes simple ideas are easy to miss, and GTD is so simple and common-sense based that its easy to overcomplicate it. I've been guilty of it more than once. This forum helps to keep me on track and it keeps the fundamentals of GTD fresh and real to me.
I'm so grateful that we have this forum and I'm grateful to everyone who has have posted questions and answers here. I've learned at least as much from this forum as I have from David Allen's teachings.
