I have about 40 pages left but I'm going to go ahead and rate this 5 stars for being a fabulous introspective (oh hey, a punny!) look into introversion/extroversion and how these roles play into our society and others. I learned lots and lots about myself and others through this book and will be recommending it to many people - and especially anyone who has any interest into understanding my own somewhat socially-abnormal behavior. ;)
