Maybe my favorite book ever. Read many times. Incredibly rich. It's a great overview of the lessons of Charlie Munger (partner of Warren Buffett) - and his approach to checklists of multi-disciplinary models to guide clear thinking. Main point: if you can just avoid mistakes, you're doing better than most. So it's a catalog of the most common or important mistakes. Focused on investing, but can be applied to life.
