Warren Buffett’s Early Life and Education

Warren Edward Buffett was born on August 30, 1930, in Omaha, Nebraska. His father, Howard Homan Buffett, was a stockbroker and U.S. Congressman, and his mother was Leila Stahl Buffett. 

Warren was born second of the three children; the first was his older sister, Doris Buffett, who was a retail philanthropist and died in 2020. The third one is Roberta “Bertie” Buffett Elliott, a philanthropist and donor to Northwestern University.

From childhood, Warren showed an intense interest in numbers, memorizing city populations, statistics, and doing complex arithmetic. At the age of 6, he went to his grandfather’s grocery store and bought six packs of Coca-Cola for 25 cents. Then, he sold each bottle for a nickel and made 5 cents profit.

Warren completed high school in Washington, D.C., in 1947. During his teenage years, he was already a successful investor. At the age of 16, he had to enroll in the University of Pennsylvania’s Wharton School because his father urged him to do so. 

After getting enrolled, he wanted to leave just after one year, as he felt the program was too theoretical. Then, he was transferred to the University of Nebraska–Lincoln, where he completed his Bachelor’s of Science in Business Administration at the age of 19 or 20.

For his graduation, he applied to the Harvard Business School, but was rejected. After getting rejected, he then went to the Columbia Business School, where he earned his master’s degree and studied value investing under none other than Benjamin Graham.

How Warren Buffett Started His Business Journey

Warren Buffett started his business journey at a surprisingly early age. He started by selling chewing gum and weekly magazines, which he sold door-to-door. He also delivered many Washington Post newspapers, through which he earned a lot of money during his teenage years.

Early hustles of Warren’s business journey:

• Selling Door-to-Door
• The Paper Routes Business
• The Pinball Venture
• The First 6 Shares
• The Farmland Ownership

Warren Buffett’s First Investments and Businesses

The story of Warren’s first investments and businesses takes us to his teenage days, where he sold papers and magazines, started a business, and bought shares.

Before hanging out a lot at his father’s brokerage firm, he ran a profitable pinball machine business in a local barbershop. He bought the machine for just $25, and after expanding it in several shops, he sold it for about $1,200.

At the age of 11, he bought 6 shares of Cities Service Preferred, 3 for himself and 3 for his sister, each for $38. The shares quickly fell to $27 before bouncing back to $40. After this, he sold the shares and learned one of his first lessons: patience, as the shares later surpassed $200.

When he reached 14, he was already running his huge paper route business. He also bought a 40-acre farm for $1,200, which he saved from this paper business. From 14 to 16, he was studying and creating a passive income from his side hustles, which also made him different from other kids his age.

How Warren Buffett Built Berkshire Hathaway

Until Warren Buffett arrived, Berkshire Hathaway was a failing textile mill. In 1962, he bought the shares of the company and took control of most of the shares in 1965, due to dissatisfaction with management over a broken buyout promise.

Later, he purchased the National Indemnity in 1967, marking his entry into the insurance market and creating an economic foundation for Berkshire Hathaway. In 1972, he purchased another company, See’s Candies, with Charlie Munger’s guidance. By 1985, he shut down the textile mills that were horribly unprofitable for him.

For approximately 20 years, Buffett kept operating the textile business of Berkshire, but continuously directed the capital into insurance and other notable businesses. Then, in 1985, he chose to close the textile operations of the company.

Warren Buffett’s Investment Philosophy
