Those who learn how to minimize the damage when they are wrong and who readily own up to the mistakes they make will do far better over the long haul. Making mistakes is a part of this game, but knowing how to handle them is everything. Likewise, if you attach your ego to your portfolio’s performance you are destined for failure. The market absolutely loves to kill those with big giant egos and who look for the markets as a place to prove how smart they are. Markets chew and spit out these folks routinely for good reason and they will continue to do so at every available opportunity.
