Many successful leaders react to anxiety by working harder, holding themselves and others to an impossibly high standard, or trying to control things that are beyond their power. For them, it’s hard to imagine not fussing over every project and detail in their work lives, not taking responsibility for everything or always giving their all. “People respond to anxiety by trying to be more perfect and more in control,” Boyes says. “They not only have a Plan B but Plans C, D, and E.” In many societies, those behaviors are rewarded. We think of it as a “good work ethic,” but often perfectionism and overwork only cause further anxiety — in yourself and others.
