Well, I got sick of hearing about "GTD" and decided to read it. I like to be organized and productive and since my job has many different angles, it is necessary. The book is good, but I'm not going to go full force on the method. It confirmed some things I already do ("the two minute rule") and off...
i'm not a big fan of self-help books, but I found this book useful. I'm not entirely successful with his system, but I do a fair imitation.
