Buffett’s Legacy as a Teacher and Investor

Over the years, Warren Buffett has taken on numerous roles—best known as Omaha’s stock-picking sage. He embodies, in many ways, the complexities of capitalism. But for many in the business world, this 95-year-old figure has also been something more: an educator.

His remarkable blend of success and wisdom has made him a global icon among investors. Eli Lilly CEO David Rix even referred to him as “at the pinnacle of our nation’s business leaders.” Through his insightful letters to shareholders and engaging annual meetings, Buffett has shared invaluable lessons with CEOs around the world—not just about business, but often about life itself.

This week, Buffett, a fixture among the world’s wealthiest individuals, will step down from his position at Berkshire Hathaway, passing the baton to Greg Abel.

As this iconic investor prepares to leave his high-profile role, various business leaders have reflected on the important lessons that Buffett imparted.

During my time as a journalist, I’ve come across countless financial reports, but none have been as captivating as those from Berkshire Hathaway, primarily because Buffett is such an excellent communicator.

He has a knack for stating what he means without resorting to complex jargon. His humor, too, added a unique flair that made following his career entertaining.

Kayak CEO Steve Hafner noted, “What I’ve always admired about Warren Buffett and [his late partner] Charlie Munger is their ability to use simple language to clarify complex ideas.” He added that it requires considerable skill to break down intricate concepts into understandable parts.

Hafner also mentioned how the duo’s dry wit turns their shareholder letters into enjoyable reads.

Some of these letters contain nuggets of wisdom:

• “You only learn when the tide goes out.”
• “Forecasting rain is not important. Building the ark is.”
• “I reluctantly gave up the idea of continuing to manage the portfolio after my death.”

A common theme among the CEOs who spoke to CNN is Buffett’s legendary determination. He is known for accumulating large amounts of cash at Berkshire and waiting patiently for the right investment opportunity. When he does invest, he often maintains that commitment long-term. “Our favorite holding period is forever,” he stated in a letter to shareholders in 1989.

Investor and entrepreneur Anthony Scaramucci reached out to Buffett 30 years ago, sharing that he bought Berkshire stock for his daughter. “Since she was only a year and a half old and expected to live to 84, that meant she could hold that stock for 82 and a half years,” he recalled.

Buffett responded quickly, pointing out that a focus on short-term results was misguided and emphasizing his own preference for a century-long investment horizon.

Buffett, often seen as a shrewd capitalist, has amassed significant profits, including billions from Goldman Sachs. Yet, he maintains strong ethical principles.

“I learned from Warren Buffett that excellence is a discipline,” remarked Larry Restieri, CEO of Hightower. “Establish a clear direction, stick to your values, and exercise patience in your actions.”

With a net worth around $150 billion, Buffett is undoubtedly successful, but he has always stressed the importance of honesty and integrity.

He expected the same commitment from his collaborators: “If I lose money for the company, I’ll accept it. But if I damage the company’s reputation, I’ll be ruthless,” he once stated in front of Congress.

Buffett is also known for enjoying a private life filled with flying and a deep appreciation for Cadillacs. He is incredibly rich but expresses no regret for his wealth.

However, he chooses to pass on a considerable portion of his fortune. Along with Bill and Melinda Gates, Buffett committed to the Giving Pledge in 2010, which encourages wealthy individuals to donate the majority of their fortunes either during their lifetimes or in their wills.

Marcel Arsenault, CEO of Real Capital Solutions, who signed the pledge, remarked, “Warren inspired me to think beyond financial success.”

Buffett explained his philosophy by stating, “Very often, vast collections of property end up in the hands of their owners.”

Yet, he noted that giving doesn’t necessarily equate to large financial donations.

“When you help someone in a thousand ways, you help the world,” Buffett stated in 2025. “Kindness doesn’t cost anything, but it’s also something you can’t spend money on.”
