I feel like the authors of many non-fiction books (e.g. business, self-help) are told that they must write a 320 page book, even if the core is, at most twenty, pages. I guess it needs to look plump on the shelf at the airport or something. Dale Carnegie got a lot across in a small number of pages. Today he’d have to do 320 pages or maybe even two books one on making friends and one influencing people. I wouldn’t mind paying for the book if there was a way to get the wheat without the chaff. I’ve seen various book summary apps but I’d rather get it straight from the author minus 300 pages of filler.
