To play devil's advocate, I think there is a relatively small overlap of 1) very successful people in finance/tech/etc and 2) people that dedicate enough time to effectively communicate ideas in a book/blog There are exceptions, Ray Dalio being a recent good example. But I think he is more the exception, not the rule. Below is a related passage from Essentialism that touches upon this dynamic: "Jim Collins, the author of the business classic Good to Great, was once told by Peter Drucker that he could either build a great company or build great ideas but not both. Jim chose ideas. As a result of this trade-off there are still only three full-time employees in his company, yet his ideas have reached tens of millions of people through his writing." McKeown, Greg. Essentialism (p. 55)
