I considered reading it, but then I read a review that says that although it’s useful, it presents a few quite manipulative tactics:
“A lot of what affects how much you enjoy these books is, again, how self aware you are or how much consideration you've given to how you talk to people and the best way to get what you want from others. If you already easily have any easy time convincing people, or have thought about it and are self aware of how you behave and talk to others then I don't think any of these things are going to be surprising or helpful but if you haven't ever actually considered the way you interact with people then maybe this will be an eye opening book for you. Personally I think I've always been a little manipulative so I wasn't all that impressed. The writing was average also so the books clear and easy to read but I wasn't impressed by the writing either.”
