I’ve heard of David Allen and his “getting things done” (or “GTD”) method a number of times in the past and finally decided to read/listen to his classic book which first came out in 2001. I must have been reminded of him recently in some way, although I don’t remember just how, and I got the audio book from the library. It’s read by the author, who sounds very engaging and thoughtful, and I was really fired up by his introductory chapters. Then he kind of lost me as he headed into the chapters that delineate exactly how you’re supposed to do things his way. Most of his work has been done in the business world, and so many of his examples are drawn from that arena. I think that was part of why I drifted away.
