This was a book that was very comforting to read. 
 The book starts with a reaffirmation of what good introverts can do, the benefits of having a quiet, but firm sense of morality, and the present preoccupation for extroversion and group collaboration among business schools and many current educational standards. So far, so good. 
 Some of the social science later on is a bit shaky - Asian-Americans being held up as a blanket group, blaming extroversion for some aspects of the early financial crisis. 
 But this is closed up with the usual means of coping or enduring large group exercises, and when introverts can pretend to be extroverts, if only for a little while, and then promptly return to their quiet comforting environments. 
 The fellow introverts out there will naturally appreciate this comfort. But how are the extroverts to be convinced? This is my question.
