Susan Cain's book "Quiet - The Power of Introverts in a World That Can't Stop Talking" was a revelation for me when it came out a few years ago. As a self confessed introvert, it helped me to understand more about myself as well as others, especially those closest to me.

I think it is important to help identify the situations and environments that we thrive in, and also to balance those out with other experiences as well.
