My experience with the book has been that I've got far more from it than I expected.
Every area of life, whether in interaction with others or your own internal dialogue, involves language and persuasion skills, making this material applicable to every situation. I received the book, 166 pages which break down a large and complicated area into small, simple chunks that are easy to understand and apply immediately in the real world. The emphasis on practice, the presentation of the material, and many other factors combine to take you to a point where the material impacts your thoughts and actions, which means that daily communication is never quite the same again.
In the book it is said that the skills can be learned with a daily time commitment of just ten minutes. While I agree this is possible, I found I was spending longer in order to learn and practice the skills. One thing I would like to have seen was a concise list of all patterns covered at the end, with a brief description of each, for an at a glance reminder.
The issue isn't necessarily being given the patterns and conversation models, but how they are given, in order to make them straightforward to use, which is exactly what this book achieves.
