“Many of us are uncomfortable with the idea of taking on a “false” persona for any length of time. And if we act out of character by convincing ourselves that our pseudo-self is real, we can eventually burn out without even knowing why. The genius of Little’s theory is how neatly it resolves this discomfort. Yes, we are only pretending to be extroverts, and yes, such inauthenticity can be morally ambiguous (not to mention exhausting), but if it’s in the service of love or a professional calling, then we’re doing just as Shakespeare advised.”
