"Charlie Munger's Wisdom for a Long, Happy Life: Avoid Crazy and Mega-Mansions"

Billionaire Charlie Munger, who passed away at the age of 99, attributed his success and long life to his advice of "avoiding crazy at all costs." He emphasized the importance of avoiding major catastrophes by being cautious and steering clear of obvious risks in personal and professional life. Munger defined "crazy" as behaviors such as excessive drinking, smoking, and leveraging investments. He and his business partner Warren Buffett intentionally ran their investment holding company, Berkshire Hathaway, in a cautious manner to protect shareholders. Despite his caution, Munger admitted to indulging in minor vices like peanut brittle and Diet Coke, acknowledging that they may shorten his life but stating that he doesn't care.
