„(In writing Quiet) I was fueled by the same mix of passion and indignation that I imagine inspired Betty Friedan to publish The Feminine Mystique in 1963. Introverts are to extroverts what women were to men at that time--second-class citizens with gigantic amounts of untapped talent. Our schools, workplaces, and religious institutions are designed for extroverts, and many introverts believe that there is something wrong with them and that they should try to "pass" as extroverts. The bias against introversion leads to a colossal waste of talent, energy, and happiness.“
