"In the fall of 1974 I was in graduate school at USC taking a portfolio-management investment course. The financial markets were in difficulty, and I didn't understand how securities were being sold at such depressed levels. I had only recently discovered Security Analysis by Graham and Dodd when we had a guest lecturer come in named Charlie Munger, who went on about this idea of value investing. After the class was over, I walked up to Charlie and asked him if there was one thing that I could do that would make me a better investment professional. His answer was, 'Read history, read history, read history.' And so I became a good historian, reading both economic and financial history as well as general history.
