Women in business and professions know they must sometimes be masculine, sometime feminine. Can women do this “shifting” without burning out or losing themselves? It is natural and smart to select from different “versions” of ourselves when we move from one situation to another. But it can be costly. If a woman who prefers a feminine style has to behave in masculine ways a lot, she may become an “honorary man,” become exhausted or dis-engage. If she does so consciously, intentionally, “mindfully,” can she avoid these costs?
