The book showed me what skills we need - to understand the feelings of others and build normal relationships with people. It offers tips on how to improve your own skills.
I definitely recommend the book, and I can say for myself: I have already started using the tips from this book, so look at me in a couple of months and you will absolutely not recognize me.
P.S. I'm kidding
P. P. S. Or not
By the way, the book is worth reading ;)
