Charlie Munger, the legendary investor and longtime Berkshire Hathaway vice chairman, built his success on caution, discipline, and a no-nonsense approach to life and business. Rejecting extravagance, he lived simply, avoided risky trends like cryptocurrency, and urged businesses to focus on what works. His influence shaped Berkshire Hathaway and Costco, where he championed long-term thinking. Munger’s legacy is a masterclass in avoiding mistakes, resisting excess, and staying rational—principles that continue to guide investors and businesses long after his passing.
