Are we doomed to repeat our investing mistakes?

Are we doomed to repeat our mistakes?

The bottom line is that even though knowing financial history is important, requiring people to study it won’t make a big difference, because they’ll ignore its lessons. There’s a very strong tendency for people to believe in things which, if true, would make them rich. Demosthenes said, “For that a man wishes, he generally believes to be true” Just like in the movies, where they show a person in a dilemma to have an angel on one side and a devil on the other, in the case of investing, investors have prudence and memory on one shoulder and greed on the other. Most of the time greed wins.  –said Howard Marks
