Once in a while you will regret having walked away. The winning set will continue without you, and you will be left morosely counting all the money you didn’t make. In hindsight, your decision to quit will look wrong. This depressing experience happens to every speculator once in a while, and I won’t try to minimize it. It can make you want to cry. But cheer up. To match against the time or two when the decision to quit early turns out wrong, there will be a dozen or two dozen times when it turns out right. In the long run, you make more money when you control your greed.
