While this book is very informative, it is also the worst book I've ever read. The way the information is laid out makes it impossible for me to retain anything, and the author has way too many dry jokes. I also don't like how learning persuasion basically means being deceptive and this whole book is about changing yourself and how you appear so that people will like you, and tricking people into agreeing with you. Overall, worst book I've ever read. If anything, go to LitCharts and read the summaries.
