@judgedread @KarlDahl More like "Pretend to not have any". Someone once rephrased the title as "How to dupe people and manipulate idiots". I only read the book in once in High School and the advice was really good, at least along those lines (the author frequently refers to Lincoln as I recall, take from that what you will). Another tact might be "How to talk to people you can't stand and effortlessly extract yourself from painful social situations"
