This is not my usual read, but I read it for two reasons. First, it was on sale on iBook. Second, Thomas wrote an excellent review of it, and he has never lead me astray as far as recommendations go. This was not just a psychology book. That word is too narrow. It is self-help and history and just a wealth of information on introverts and extroverts. Some stuff I did skim over (like the brain-wave stuff), but Cain clearly did her research, and it shows. She took us everywhere from church to Harvard Business School to back to our childhoods. I am looking to go into education so I found what she had to say about working in groups during school particularly interesting because I myself have never liked group work. Though sometimes the excessive details are too much (there are studies that could've been cut just to make it flow better), Cain makes an excellent logical argument for introverts all over the world. We salute you!
