I think this is a great book to be applied in life. Not to manipulate people but to mostly recognize who is or isn’t on your side.
Let’s just say, we playing game of chess, this book is helping you to think a head and notice red flags, and it helps you make the right move to protect your self against those who would harm you, because let’s be honest, all people have friends, some have a lot and some don’t have friends (sadly) people that have friends are often involved in some type of drama, weather friendships got mixed up at work and conflicts came up, or boyfriends and girlfriends relationships, one is using the other, or the other way around.
This book is very very very helpful, 10/10 I would recommend to read this.
