In the United States and many other western cultures, society is built to favor the extrovert. When it comes to the education system or even making career gains, extroverted personalities seem to be put on a pedestal. Quiet describes how introverts are undervalued, but behind the scenes, many of the world's greatest innovations and ideas have come from introverted personalities.
A simple way to think of the differences between extroverts and introverts is by the kinds of activities that require more mental & emotional energy and the activities that recharge them. Extroverts can gain energy from being around other people, whereas, after a while, that can be a very draining activity for an introvert. An introvert can be by themselves and recharge, whereas being alone can be a draining activity for an extrovert. Introverts are more motivated by internal factors, such as fear and often think first and prefer listening as oppose to speaking. Extroverts are more motivated by external factors, such as rewards and often act first and prefer to do the talking.
Quiet does talk a lot about the work and career implications of being or working with an introvert, so you can learn to mesh better with a team or correct misperceptions about people you work with who tend to like their quiet time.
Quiet is backed by a lot of research and written in an approachable manner with excellent narration. It's awesome for both extroverts and introverts.
Quiet has been on my reading list for a very long time. I watched Susan's ted talk and was inspired to read her book even more. Growing up very shy and introverted I wanted a better understanding of this personality trait and was curious to hear stories of how people have made this trait work for them.
