I'm insatiably curious about human nature.

Solitude matters. And for some people it's the air they breathe.

Introverts need to trust their gut and share their ideas as powerfully as they can. This does not mean aping extroverts; ideas can be shared quietly, they can be communicated in writing, they can be packaged into highly produced lectures, they can be advanced by allies. The trick for introverts is to honor their own styles instead of allowing themselves to be swept up by prevailing norms.

(Finland is a famously introverted nation. Finnish joke: How can you tell if a Finn likes you? He's staring at your shoes instead of his own.)

Many people believe that introversion is about being antisocial, and that's really a misperception. Because actually it's just that introverts are differently social. So they would prefer to have a glass of wine with a close friend as opposed to going to a loud party full of strangers.
