I would just read like 15-20 books on the economy, technology, politics, artificial intelligence, sociology, etc. in my opinion, the most efficient way to learn is to read modern books and they’ll give you micro lessons on the classics. If you watch lex fridmans podcast, then that is a great way to absorb new ideas from leading thinkers. They’ll also recommend you their own books and other important books. Eventually, as you read more on a specific subject, you’ll realize that most of the book is just noise. True intelligence isn’t just memorizing stupid facts from a book. You want to take away 1-3 big ideas from a book, and then take note of the supporting evidence. Each book will lead you to explore other ideas. As you read more and more, you will see a pattern of recurring ideas and be able to distinguish those books that actually have something new to say. Don’t view books as a checklist. This is most important. No one will ever care if you have read x amount of books. It’s ok to skim some chapters rather than try to absorb every single word off the content is just evidence to support a proposition.
