Summary

A book that has had a large impact on how I think and approach problems.  Formatted after Ben Franklin’s yearly publication of advice, Munger lays out all sorts of things, from clear investing principles, to an introduction to mental models and how more people should be thinking with interdisciplinary tools. Particularly relevant for those interested in business and finance, but as he makes clear in many of his speeches (transcripts included in the book), it should be relevant for all, from lawyers to economists.  Highly recommend.
