One of the best rules anybody can learn about investing is to do nothing, absolutely nothing unless there is something to do. Most people – not that I’m better than most people – always have to be playing; they always have to be doing something. I just wait until there is money lying in the corner, and all I have to do is go over there and pick it up. I do nothing in the meantime. Even people who lose money in the market say, ‘I just lost my money, now I have to do something to make it back.’ No, you don’t. You should sit there until you find something.
