“I think it’s almost impossible…to do well in equities over a period of time if you go to bed every night thinking about the price of them. I mean, Charlie and I, we think about the value of them… Focusing on the price of a stock is dynamite, because it really means that you think that the stock market knows more than you do…. The stock market is there to serve you and not to instruct you.”
—Warren Buffett.
