I'm struggling to get through TFaS, really don't understand how it became such a 'PopPsych' (if that's a thing) classic.
It's like a collection of the obvious, the wrong, and autobiography of someone you haven't otherwise heard of.
Of that class of book, the game is to pretend to have read it. A little like quoting a play having read a book of quotes.
It'a probably obvious to you because of cultural osmosis.
