Poor Charlie's Almanack: The Essential Wit and Wisdom of Charles T. Munger
by Charles T. Munger & David Clark
If you're burning out from chasing complex solutions while ignoring fundamentals, Munger's wisdom will ground you. He teaches that avoiding stupidity and mastering the basics beats seeking brilliance every time.
Inversion: Instead of asking how to succeed, ask how to fail. Then avoid those things. 'All I want to know is where I'm going to die so I'll never go there.' Flip the problem to see what NOT to do.
