I'm glad for the insights gained from this book. It's got a lot of valuable information about the meaning behind body language. I think the most valuable insight is to identify the needs of the other person and meet it.
Now for the bad.
I don't like the way Chase frames how to interact with people. He talks about narcissists in interviews I've seen, and has studied human behavior for years, but it's pretty obvious he has little to no self awareness that he's a narcissist himself.
Throughout the book, he speaks in terms of information harvesting, and covertly getting what you need from people. It's almost as though he sees himself as a thief, and people as objects. He steals what he needs from them without their awareness, and why? Never to benefit them. Only to benefit himself - and how cool that you can do it too! Throughout the book he directly tells people to lie to gather Intel.
Question to ponder: Should I trust someone who tells people to lie to get what they want?
One of the biggest benefits for me was to realize that there are a lot of people like Chase out there. It's valuable to see how they are trying to manipulate me through tactics and only to get what they want. This book is a window into the mind of people with ulterior motives.
While I was reading this book, I was also reading "How to Win Friends and Influence People". The contrast between the two books couldn't be wider. I assumed that book was about manipulating people, but it's not. It's about being a sincere and humble person. What you'll find in that book is going to take you further than what you'll find here (and it's free to listen to on YouTube!).
All that said, I'm glad I read the book to understand this world of interacting with people from both perspectives. I'll take the few nuggets I gleaned with me, because after all they are there.
A few other notes:
1. The first chapter is a sale to get you to buy the book. Just skip it if you've bought it, and if you read it with the thought of buying it, know that this guy makes money training salespeople. He's very persuasive, but that doesn't mean the product is good.
2. To get you to keep reading he constantly uses language like, "In the next chapter I'm going to reveal something I never thought I'd reveal to the public." This is a hook, to hype up the content to make it sound more extraordinary than it is. Super baity. If he was really confident in his product, he wouldn't feel the need to write a chapter to bait you in, or keep baiting you to read. (See, look at me. I'm profiling the author. Looks like I learned something.)
3. I skipped several chapters, especially towards the end. It wasn't worth my time to read about the art of persuasion through reflecting audio/visual/kinesthetic language, or pronouns, and adjectives. Literally, that last sentence sums up three chapters.
4. Others mention this, and it's true. Chase uses poor grammar. One sentence didn't make sense at all, and he forgot to finish another paragraph altogether. I think it's possible he really wanted to get the book published just so he could make some money. My sense is that's really what he's really after. Money and fame, without a lot of substance. He hacks the minds of his listeners and readers to get what he wants. You're the product.
5. The last several chapters are about his note taking system and have very little value, unless you want to follow his precise note taking method. Personally, I skipped them. He also scatters this throughout the book, probably to make the book a bit more plump. The helpful material is probably 40 percent of the books actual size. Not good for marketing to sell a book that's just over a 100 pages, so he had to air the tire.
Bottom line, if you want to know how a narcissist hacks people to get what he wants, read this book, but I'd say save your money and read someone else.
