I try to re-read this book periodically to re-fresh myself of the basic ideas and principles of it. I am not a full "GTD" adapter, but I do find that some of the ideas within has made a big difference with getting myself organized and staying on track ("two minute" rule, filing ideas, etc..)

I highly recommend this book to anyone who is feeling like they overwhelmed with paperwork, communications, taskwork, or any combination. I especially recommend this book to people who think they are organized (using a calendar, planner, lists, etc); and yet still feel like they never getting anything accomplished - this book is very useful on zeroing in on why that may be happening.

Its sort of an odd book to read, because on one hand, you spend alot of time going "well, DUH, that is just all common sense!" but at the same time, it ends up being all common sense that you are probably not doing, and if you start, makes a big difference your productivity levels.
