I'm not sure it's exactly what you're looking for, but there is a book "How to win friends and influence people" by Dale Carnegie - despite it's cheesy title and being pretty old, it's still very good advice. Turns out, people nature don't change that much !

Although I agree with you every time I think of that book I'm reminded that Charles Manson read it in prison and it no doubt helped him is his later years.

This is probably one of the best unintentional advertisements for the book’s effectiveness.

Seconded this book. Non-violent communication is another one. Also check out Healthy Gamer on YouTube.
