Read cluster of books on a subject for maximum ROI

According to Slava:

one book gives you more knowledge about a subject than almost every other person on the planet, because people don’t read. Two books on the same subject give you more knowledge than almost any reader, because people don’t read two books about the same thing. Beyond two books on a subject, there is a long utility dip. . So two books on a subject, at least with respect to competitive edge, is an inflection point. After you read two, you get diminishing returns.

This is a measurable, doable system for Skill Stacking

Select a cluster of books that allow you to look at the world from a lense of “Study X though Y”. Examples: a) Study American History and dynamics of failure by studying the biographies of presidents who sought relelection and failed. b) Study American History through technological expansion.
