Regarding:
The Psychopath Test: A Journey Through the Madness Industry

This book has had some criticism because apparently the author didn't actually have some of the conversations he described. Nevertheless, I think it's important because it shows you you start to see the symptoms all around you and start to suspect EVERYONE who is rude to you of being a psychopath.
Don't fall into the trap of attributing mental illness to everyone who done you wrong.
