This is a book about different speeches from Charlie Munger
It is a bit psychological / philosophical about how to trade, live or just making decisions. Life is always changing and one must adapt and always keep learning/reading.
The main thema is the multidisciplinary so one can different mental models to discover a pattern. He gives a lot of stick about how badly is psychology taught in schools and universities (although he has only read a couple of books!) It mention the importance to have check-list (like pilots, surgeons, etc) and practice your mental models!
Their investment has been always long-term and based on compound-interest and rarely in Tech companies. I think their strategy is very different from Investment banks, Hedge Funds, etc. But I wonder if that model is going to carry on working in a market where those long-term investments are going to be still valid.
Anyway, I will not be rich or good investor (not my goal) but interesting the focus in keep learning/reading and having different models in your head to try to understand the world.
