Charlie Munger hasn't written a book, but he may as well have, because there are those among us who have compiled his speeches into a 350-page text. The work is available here for free.
There's some great stuff in these pages. I've read much of it before over the years, but it's really helpful to get a refresher. In particular, I love his speech on the psychology of human misjudgment that opens the compilation.
The book is made up of a few speeches followed by several years of remarks (including question and answer sessions) made at Wesco annual meetings, which Munger chaired.
The book doesn't feel like it's 350 pages, mostly because there is a lot of repetition. A lot of people ask questions that were already asked in previous years, and Munger also sometimes answers different questions with the same answers. If you're already familiar with Munger, you'll probably also recognize a lot of his more famous sayings.
