I discovered the wisdom of Charlie Munger a few years ago and have been obsessed with his concept of Mental Models for solving both complex and everyday problems. I’ve been slowly working through mastery of each mental model recently as a refresher and to tackle some new challenges in life and business. I highly recommend going through the list and rank you knowledge of each from 0-5 (0 being no knowledge and 5 being mastery of the mental model). While I wouldn’t call myself a master of any of them yet, I have self-ranked 3-4 on a few of them that I find most useful and use frequently. Hope you enjoy!
