The comment by Sunnyschool, at 8 am Mon, Feb 20 mentions a key book. Quiet is far from just a “study of introversion”. I gave this book to my introvert child for Christmas, and it affirmed that kid’s sense of our American values which lean toward extroversion. But the numbers show the Quiet tendency is far from a “fringe” or slim minority. It is THOUSANDS of college kids, creators, inspiring leaders, and basically, pillars of our world, our society.
