Super repetitive, but still well-written and interesting. My big ick with this book is that it reads like a manual for sociopaths. The author seems to view friendships as less mutualistic and more competitive (typical capitalist mindset).

Do not use this book as a formal guide! Noting down people's names and birthdays could be weird, and using their first names in the beginning of every sentence makes you sound like a rookie car salesman. Reading the room is an important but soft skill that is better learned from experience than theory.
