• Buffett discovered Graham was on the board of GEICO insurance at the time. After taking a train to Washington, D.C. on a Saturday, Buffett knocked on the door of GEICO's headquarters until a janitor allowed him in. There, he met Lorimer Davidson, the vice president, who was to become a lasting influence on him and life-long friend.^[31] They talked for four hours about the insurance business. Davidson recalled that he found Buffett to be an “extraordinary man” after fifteen minutes.
• Buffett was graduated from Columbia and wanted to work on Wall Street. Both his father and Ben Graham urged him not to. Buffett offered to work for Graham for free, but Graham refused.^[30] He purchased a Sinclair Texaco gas station as a side investment, but that venture did not work out so well as he had hoped. Meanwhile, he worked as a stockbroker. During that time, Buffett also took a Dale Carnegie public speaking course.
