I finished what might be my best read of 2012. It certainly is so far. Quiet: The Power of Introverts in a World That Can't Stop Talking by Susan Cain. You can find more about it at Amazon.
If you're an introvert, or if you don't know for sure but you hear people using words like shy, loner, aloof, quiet, reserved, and many more of that ilk to describe you, you need to read this book.
It's hard to live in this loud and noisy world, especially when you prefer quiet and thoughtfulness to yammering on out loud about nothing, at least without thinking something is wrong with you. In addition, you can expect that you'll not advance easily through the corporate ranks for this very reason: Management, at least the weak kind, tends to select for more of itself, and if they like busy social occasions, cocktail parties, and the large dinner table all with their multiple concurrent conversations, you can expect that you really won't be needing that new suit, no matter what other talents you have. You'll need Lady Luck on your side.
I could go on about the systematic extermination of introverts in American culture and the endless losses we sustain when our fake leadership doesn't bother to seek the thoughts of the quiet people who usually bother to think about what they might say, not that such leadership would pause to listen, much less ever ask in some manner that'd elicit the thoughtful response. Nope. I'm not going on about all that. Instead, I'm sending Ms. Cain a thank you note.
