Reading Psycho-Cybernetics once tells you very little. Andrew Treantos worked through it chapter by chapter and wrote each one up: the failure mechanism and how to turn it around, rational thinking, the do it yourself tranquillisers Maltz recommended for peace of mind, turning a crisis into something creative.
He does the same with Think and Grow Rich, treating persistence and organised planning as separate problems rather than as chapter headings. Jack Canfield gets a single principle summarised and assessed. Rich Dad Poor Dad appears as a complete audio listen. A hundred lines from Tony Robbins sit in one place for the days when you need a sentence instead of an argument.
Mixed in with all that are the strange ones. There is a set of search operators for locating files that nobody meant to leave findable, a method for getting very cheap clicks on Facebook advertising, and a genuinely alarming lift prank filmed in Brazil.
If you own a shelf of personal development books you have never finished, start with the chapter summaries. They come closest to having the thing read aloud to you.
