Tren Griffin, author of Charlie Munger: The Complete Investor and the 25iq blog, joins Jim O'Shaughnessy on Infinite Loops to talk about why writing a book is rarely about money, how AI is reshaping writing and publishing, why every author is really starting a business, how to build a book in public, the Charlie Munger lesson that changed his life during the dot-com boom, whether serious reading is really dying, and how to find a passion worth following.
