Buffett must have been excited as he entered the classroom; Benjamin Graham, the author of “The Intelligent Investor,” was the one teaching the class at Columbia Business School.

As Warren Buffett later remarked, “If I hadn’t read that book in 1949, I’d have had a different future.”
Buffett, like many other investors, has been shaped by Graham’s legacy. Although the billionaire can trace many lessons from Graham’s teaching, there are two lessons that Buffett has employed…
