4.0

Being an introvert, I really liked this book. It really did validate a lot of the things I think and do and gave me confidence to continue being the way I am (especially understanding the biological aspect of introversion). I did feel the book was a little one-sided at times, assuming the reader understood the favoritism of extroversion. I have never once believed that extroversion was an an incredibly positive trait so I felt that Cain's brushing over the benefits of extroversion was rash.
