Quiet: The Power of Introverts in a World That Can't Stop Talking by Susan Cain.
Spoiler:
Amazon Best Books of the Month, January 2012: How many introverts do you know? The real answer will probably surprise you. In our culture, which emphasizes group work from elementary school through the business world, everything seems geared toward extroverts. Luckily, introverts everywhere have a new spokesperson: Susan Cain, a self-proclaimed introvert who’s taken it upon herself to better understand the place of introverts in culture and society. With Quiet: The Power of Introverts in a World That Can’t Stop Talking, Cain explores introversion through psychological research old and new, personal experiences, and even brain chemistry, in an engaging and highly-readable fashion. By delving into introversion, Cain also seeks to find ways for introverts and extroverts to better understand one another--and for introverts to understand their own contradictions, such as the ability to act like extroverts in certain situations. Highly accessible and uplifting for any introvert--and any extrovert who knows an introvert (and over one-third of us are introverts)--Quiet has the potential to revolutionize the “extrovert ideal.” –Malissa Kent
