I enjoyed this book, she shared how America in the early 1900s switch from a focus on character to a focus on personality, and how this has had some harmful results. She showed how we have so glorified the charismatic, confident extroverted personality, that introverts feel they have to fit this mold. Susan Cain then shares some of the many strengths of introverts in the context of education, parenting, leadership, public speaking, business, relationships and culture. She also shared lots of interesting studies concerning personality theory. I now have a little more of an understanding of why I am so bothered by violence and anger and that it actually has something to do with me not having "thick skin"! It is interesting that I am wired to have a more sensitive conscience and to not be motivated by money, power and status. There was some things in this book I've not heard anywhere else, its a book I would like to see land in the hands of all my introverted friends and yeah, even extroverts could benefit from reading it, for it could give them a better understanding of us introverts.
