A small, quick and easy-to-read book that aims to describe a single idea — A very clever idea, indeed — capable of dramatically increasing the productivity of the writers who implement it. I believe that, in this case specifically, the value of the book is directly linked to the results the readers are able to reach. I just read it and I could not implement any of the techniques presented by the author yet. However, I believe that they must be adapted to my reality and my writing style, and that the same should happen to the absolute majority of readers. Even so, I'm very optimistic now.
