I got so much out of reading this book. I picked it up on a whim, wondering what the advantage of an introvert might be, suspecting that I was one. Goodness me, I had no idea I was so introverted, or how much of my life it really impacted. Now, all these little nonsensical things about myself throughout my life suddenly have an explanation, and more importantly I feel validated for being me! I got 26 out of 30 on the book's questionaire, so I can proudly call myself an introvert. Marti helped me understand also that, being left-brained, I'm quite happy living an introverted life, whereas my sister, a right-brained introvert, struggles with the limitations. It was also surprising to find that my husband is fairly extroverted and the relationships section has been really helpful for me to understand where he's coming from and how we can get along better.
If you even slightly suspect that you are an introvert I highly recommend reading this book. You will feel much better about yourself, even if you didn't feel badly to begin with!
