Introduction:
On February 25, 2025, India's English-language business daily, The Economic Times, introduced Charlie Munger to over 800,000 readers in an article titled "How Warren Buffett's right-hand man Charlie Munger built an empire by learning what not to do?"
As Munger often quipped, "I just want to know where I'm going to die, so I'll never go there." Munger consistently steered clear of trouble in life and avoided mistakes in investing. Drawing on this insight, The Economic Times has compiled Munger's distinctive wisdom on both investing and living.
1. Avoid all common ways of failing
Charlie Munger, the legendary investment guru and Vice Chairman of Berkshire Hathaway, has built his success on prudence, self-discipline, and a pragmatic approach to life and business. He shuns extravagance, leads a simple life, steers clear of the trendy yet high-risk cryptocurrency, and urges companies to focus on what works.
His influence has shaped both Berkshire Hathaway and Costco. At both companies, he consistently championed long-term thinking. Warren Buffett's life stands as a masterclass in "avoiding mistakes, resisting excess, and maintaining rationality"—principles that continue to guide investors and businesses worldwide even after his passing.
Charlie Munger passed away in 2023 at the age of 99. During his lifetime, he dismissed the notion that "massive wealth stems from some secret formula." Just weeks before his death, in an interview with CNBC's Becky Quick, he flatly rejected this idea.
"I don't know any secret," Munger said. Instead, he adheres to a simple philosophy: "I've steered clear of every common way to fail, because my rule for survival is to avoid all the standard paths to failure."
Munger's philosophy is rooted in prudence. "If you teach me the wrong way to play poker, I'll steer clear; if you teach me the wrong way to do anything else, I'll steer clear as well," he explained. Munger's strategy is simple: stay far away from reckless decisions and unnecessary risks.
2. A Life of Frugality and Focus
Unlike many billionaires, Charlie Munger never indulged in a lavish lifestyle. He lived in the same modest home for 70 years, refusing to follow trends and build a mansion. He once remarked about homes: "In almost every case, a luxury home makes people less happy, not happier."
Munger's financial discipline extends beyond his personal life. He is highly critical of reckless behavior in the financial sector—particularly in the realm of cryptocurrencies. "I sometimes call it 'crypto junk,' and other times 'crypto trash,'" Munger said. "The very idea that anyone would buy such things is simply absurd." In a February 2023 interview with CNBC, he stated that, in his view, digital currencies are "utterly mad, foolish gambling."
His skepticism of wasteful spending also shaped his view of corporate expenses. When his longtime business partner, Warren Buffett, defended the purchase of a $6.7 million corporate jet for Berkshire Hathaway, Munger was unimpressed. Buffett later wrote: "In his mind, luxury travel means riding an air-conditioned bus—and he only splurges on an upgrade when there's a special deal."
Munger has always maintained a steadfast stance against reckless decision-making. "Avoid madness at all costs. It's far more common than you think," he cautioned. "It's all too easy for people to slip into madness. So you must steer clear of it—time and again."
3. Shaping Berkshire, Guiding Costco
For more than six decades, Charlie Munger played a pivotal role in Berkshire Hathaway's transformation from a near-bankrupt textile mill into a multinational corporate giant. His sharp intellect and disciplined approach shaped the company's long-term investment strategy. He opposed impulsive decision-making and urged the firm to focus on what truly matters rather than chasing fleeting trends.
His influence also extended to other companies, most notably Costco. He served on the company's board of directors for more than 25 years.
At Costco, Charlie Munger's advice has remained consistent: "Stick to our core business, values, and principles."
Director Hamilton Tony James recalled that Munger could cut through complex corporate matters with clear logic. In an interview with Chief Executive magazine, he said, "For a company as large and high-pressure as Costco, understanding the current situation can be a complicated and chaotic task, but not for Charlie. He is as precise as a compass, always able to dispel the fog and find the right path."
Munger believes there is no need for drastic change. "In the long run, the right thing to do is what we have always been doing, so don't let yourself get confused," he often reminds the Board. James admits that disagreeing with him is "a risky proposition."
Munger is not only an advisor but also a loyal customer of Costco. He describes himself as a "total addict" to the company and has stated, "I will never sell a single share." As of November 2022, he held more than 187,000 shares of Costco stock.
Costco's adherence to Charlie Munger's philosophy is evident in its pricing strategy. Since 1985, the company has steadfastly refused to raise the price of its famed $1.50 hot dog–soda combo. When then-CEO Craig Jelinek proposed a price increase, co-founder Jim Sinegal immediately shot it down, reportedly saying, "If you dare raise the price of the hot dog, I'll kill you. Figure it out yourself."
4. The Legacy of Rational Thinking
Charlie Munger's legacy is built on rationality, self-discipline, and resistance to excessive temptation. He shunned speculation, steered clear of wasteful spending, and urged businesses to adhere to what works. His wisdom continues to shape Berkshire Hathaway, Costco, and investors around the world.
For those who wish to follow in his footsteps, his advice remains as relevant today as ever: remain prudent, uphold discipline, and always avoid succumbing to "madness."
