Anyone who is an introvert knows just how difficult it is to desire isolation in a country that so values social interaction. This book really did a good job explaining how we feel; I felt that the author had done a Vulcan mind meld with me because of just how accurate the descriptions of introverted people are.
Not only does this book go into the mechanisms of what we as introverts feel, but also where we benefit. For many years, I felt that being introverted was something to be ashamed of, and now I realize that maybe it's not so bad to be this way.
In addition to the above, it goes into how extroverts and introverts can better communicate with one another. As someone married to a man who is an extrovert, I can attest that this is critical. I hope I can get him to read this wonderful book so that we can better our relationship and have an easier time communicating.
