If you are organized, don't waste your money. On the other hand, I am not and this book helped me a great deal.

First, I'd like to say that I also bought his book (which I really liked). David Allen's voice is so monotone and boring that I couldn't listen past the first 20 minutes of the audiobook. I would continue to fastforward after that thinking that his voice would liven up but to my dismay...nope...same boring voice. Don't get me wrong, he has useful info that is very helpful (I read the book) but he needs to liven it up A LOT!!! If authors aren't good at recording audiobooks then they should hire people to do it for them. They'll sell more audiobooks if they do. All authors who want to record an audiobook - take note from Tim Ferriss's audiobook (The 4 Hour Work Week). Tim Ferriss was engaging, funny and I couldn't wait to listen to it everyday!

The abridged version of GTD is missing chapters 7-11 of the book, if you do buy this version do also invest in the book, Getting Things Done. The unabridged version was just recorded in Oct of 08, it is the full version of the book and makes much more sense to the listener. Granted you cannot implement while you are listening in a car but very important information to have. I work for David Allen and wanted folks to have the correct information regarding differences in the two audiobooks.

Of all the "organization tools" available, this is the clearest and most committed to getting you organized. I did end up buying the book as the ideas are also expressed in "maps" that make a point very simple to understand. The author has spent a considerable amount of time and energy working through these concepts. No false steps here.

Get the true abridge version.
