In business, it's best to avoid letting your heart rule your head. Although picking yourself up and trying again after failure is a hallmark of an entrepreneur, savvy trendsetters recognize that sometimes, a particular project is doomed and aren’t afraid to remove themselves from a losing situation. That can be particularly tough for people in the golf industry, as they often let their love of the game dictate their actions and hold on too long when they otherwise might not be inclined to do so. Bottom line: If the project isn't what it first appeared, be prepared to dump it before too much money is committed to the idea.
