This book could have been a bit shorter. It does make some excellent points, but it also has a lot of filler on it on the way to making the good points. If you are an introvert, and I will disclose that I am introverted, you will find yourself nodding often as you read it. There is going to be a lot of validation for you. If you are an extrovert with an introvert in your life-- a loved one, a family member, maybe a child who seems a bit too quiet or less social-- then this book will go a long way to explain why those people are how they are and also how to love and deal with them.

In addition, I would have rated it higher, but there was a lot in this book that I already knew. I've taken Myers-Briggs and done other exercises and studying to know quite well about my introverted nature. So a good amount of stuff in the book I already knew. Having said that, I did find a few things of interest, and I did learn some new things. It did give me some additional ideas on how to work in a world that, to quote the subtitle of the book, can't stop talking (or rather, a world that just can't shut the hell up). For many, I think the insight may well be how the extroverted ideal is way overrated and overvalued and how workplaces, if they wish to truly succeed, need to balance things by being inclusive with their introverted folks. Also, the parts on how a lot of group work is bullshit, which I have always known since childhood (just never had the evidence to back it up) will provide good insight. It is not that collaboration is bad, but most of what passes for it in current workplaces is horrible and even detrimental. The book does give other options to make things work better.

To those in the know, the book will likely serve mostly as affirmation and validation material, which in itself is not a bad thing. To those needing to learn, this is definitely a good resource, albeit it could have been a bit shorter. I did take some notes, which I may add to my blog at some point for future reference.
