So if you are evaluating others (or yourself!) in the investment field, think out some standards - apply them - interpret them.
Warren BuffettWell, one time some attractive woman sat next to Charlie and asked him what he owed his success to, and, unfortunately, she insisted on a one word answer. He had a speech prepared that would have gone on for several hours. But when forced to boil it down to one word, he said that was "rational". You know, he comes equipped for rationality, and he applies it in business. He doesn't always apply it elsewhere, but he applies it in business and that has made him a huge business success.
Warren BuffettIt's got to be the best intellectual exercise out there. You're seeing through new situations every ten minutes. In the stock market you don't base your decisions on what the market is doing, but on what you think is rational. Bridge is about weighing gain/loss ratios. You're doing calculations all the time.
