Charlie Munger is no doubt one of the greatest minds of today. Not only an investor, but also a philosopher who I believe can be most likened to his role model, The Autobiography of Benjamin Franklin.
Munger's lessons in both life and investing are profoundly insightful. As Charlie often says, it is much better to learn vicariously by studying the folly and triumphs of others, then emulating the appropriate behavior. With that being said, another Mungerism comes to mind that I often remind myself of: A lot of folks ask for advice, but very few take it.
