Charlie Munger is one of the greatest investors of all time. Plenty of people have called him a “learning machine.” The phrase ‘Latticework of Mental Models’ comes from Berkshire-Hathaway’s Charles Munger, who spent most of his life working out ways to, for lack of a better term, think better.

Munger has come to the conclusion that in order to make better decisions in business and in life, you must find and understand the core principles from all disciplines.

You have to learn all the big ideas in the key disciplines in a way that they’re in a mental latticework in your head and you automatically use them for the rest of your life. – Charlie Munger

This is what he calls Elementary Worldly Wisdom, and using his system of Mental Models can help you succeed in almost any endeavour.
