Quiet
One of the reasons that you don't see many posts here is simply down to the fact that I'm an extreme introvert (from memory, on the Briggs-Meyers test I ended on the extreme end of I). I thus really enjoyed one of my recent reads - "Quiet" by Susan Cain (ISBN 978-0-141-02919-1). While I don't exhibit all of the anecdotes, I will admit that I did feel that I could empathise with the vast majority of them. I do thoroughly recommend this book - it opened my mind to the viewpoints of both introverts and extroverts.
