My favourite example of this is Harold Pollack who got tonnes of media coverage for coming up with 9 rules for personal finance which fit on an index card. I listened to his interview on Freakonomics, and he's now selling a 256 page book called "The Index Card: Why Personal Finance Doesn't Have to Be Complicate". 256 pages, about his rules that fit on an index card. As an aside I always hear podcast adverts for https://www.blinkist.com/ https://www.blinkist.com/ which does audio/text summaries of non-fiction books, I haven't tried it yet but it might be worth checking out.
