In a culture where being social and outgoing are prized above all else, it can be difficult, even shameful, to be an introvert. But, as Susan Cain argues in this passionate talk, introverts bring extraordinary talents and abilities to the world, and should be encouraged and celebrated.

Susan Cain is a former corporate lawyer and negotiations consultant -- and a self-described introvert. At least one-third of the people we know are introverts, notes Cain in her new book Quiet. Although our culture undervalues them dramatically, introverts have made some of the great contributions to society – from Chopin's nocturnes to the invention of the personal computer to Gandhi’s transformative leadership. Cain argues that we design our schools, workplaces, and religious institutions for extroverts, and that this bias creates a waste of talent, energy, and happiness. Susan Cain is on a mission, and that mission is to speak for those who would rather not take the spotlight themselves: introverts.
