In a category of its own, Susan Cain’s Quiet (2012) has done more to promote the understanding of introversion than any other popular work. Its blend of historical analysis and contemporary psychological and sociological research explores topics that have been traditionally ignored or pushed aside: the benefits of solitude, the challenges of shyness, the value of individual effort in education and business, and the often-overlooked creative strengths of those who are quiet. Cain’s book should be required reading for teachers, coaches, CEOs, and community leaders. I cannot recommend it more highly. My copy is filled with notes.
Additionally, Susan Cain’s TED talk, which is entitled The power of introverts, is nineteen minutes long and well worth your time.
