Susan Cain has written an exceptional highly researched book entitled Quiet: The Power of Introverts in a World that Can’t Stop Talking. Excellent reading and available also in audio. My husband and I listened to it on a road trip and gained so much insight, helping him to see his strengths as an introvert, and me as well, in order to admire, respect and love him more deeply. Well worth reading/listening to. Here is a TED talk to wet your whistle and entice you to learn more. Enjoy!
