This book ended up just as good as the title promised. The one negative I originally had, that is the repetitiveness of certain phrases, now seems obvious to me an employment of the persuasion secrets themselves. That isn't to say I didn't stop mentally rolling my eyes every time I saw "the lizard inside" or to say I didn't skim over certain paragraphs that were obviously repeating a concept I had only just read and accepted, but the value of this book is not diminished by its quirks.
I very much appreciated all the scientific evidence backing up and proving the claims, and the long sections at the end where I could look up the studies and other references if I so wished. It was also very helpful how many examples of putting the 'secrets' to work were provided. None of them really applied to me or my situations, but they allowed me to branch off and find my own solutions, solutions that never presented themselves until I saw other real-world applications in effect.
In short, I recommend this book to anyone needing to persuade anyone! Whether it be a personal relationship or an entire market segment, these secrets will ensure you have the greatest chance of success (and that you won't alternatively ruin your chances, either)!
