We don’t always talk about some of the darker sides of human psychology, but they are out there. The simple truth is that just because you don’t focus on something, doesn’t mean it’s not real.

On that note, this book discussed topics such as blackmail, manipulation, and sadism. Some people have been hurt so much that all they want, is to see the world burn. They don’t care about others, and they just use them as tools to get what they want.
If you are tough enough to face that dark side, then come on over and start reading or listening to this guide.
