I know how much the PUA community values developing and improving yourself as a person. I have two book recommendations that I wanted to share because I actually think they give a really important understanding of human behavior and psychology. I would even go as far to say these books are fundamental reading if you're remotely interested in social dynamics, human psychology and where you potentially fit in amongst it all.

Quiet by Susan Cain - I don't have enough high praise for this book. Expertly researched, remarkably insightful. It's a brilliant book. It essentially looks at the most basic of personality differences - introvert and extrovert. Cain diplomatically argues that the world has become obsessed with the 'Extrovert Ideal', all the while ignoring the power of introverts and what they can offer (introverts account for around half the population btw). Our education system and work places often promote an extrovert personality and suppress the introverted personality, through group exercises, open plan offices, mandatory class participation etc. No evidence suggests that extroverts produce better ideas, develop stronger relationships or make better leaders (in fact there is some evidence to suggest the opposite). I suspect that a lot of the PUA community are natural introverts and so I would highly recommend this book. Here's a TED lecture the author gave.

Without Conscience by Dr Robert Hare - One of the most entertaining books I have read. It's a real page turner. This is on the complete other end of the spectrum compared to the book above. Hare looks at the personality of the psychopath. You may (or may not) be surprised to learn that most psychopaths are not murderers or even locked up in jail. In fact most are out in the general population. The reason I include this book is because there is a striking similarity between the personality clusters of psychopathy and personality traits encouraged/embodied by certain pickup artists. I think if you're practising game at night at clubs and bars there's a distinct possibility you'll come across guys that score highly on the psychopath checklist - it's good to be aware. More than that though I include this book as a red flag not to become a douchebag and develop questionable sides to yourself. Self confidence shouldn't equal narcissism. Being influential shouldn't equal Machiavellian. Playing the field shouldn't equal a devastating lack of empathy. This is a great book to remind yourself that there are some scary characters out there, but also a cautionary message that they shouldn't be celebrated either.
