We often marvel at how introverted, geeky, kid 'blossom' into secure and happy adults. We liken it to a metamorphosis. However, maybe it's not the children who change but their environments. As adults they get to select the careers, spouses, and social circles that suit them. They don't have to live in whatever culture they'er plunked into.

Evangelicalism has taken the Extrovert Ideal to its logical extreme...If you don't love Jesus out loud, then it must not be real love. It's not enough to forge your own spiritual connection to the divine; it must be displayed publicly.

INTROVERTS are especially vulnerable to challenges like marital tension, a parent’s death, or abuse. They’re more likely than their peers to react to these events with depression, anxiety, and shyness. Indeed, about a quarter of Kagan’s high-reactive kids suffer from some degree of the condition known as “social anxiety disorder,” a chronic and disabling form of shyness.

Opposites attract, and I think temperament is so fundamental that you end up craving someone of the opposite temperament to complete you.

Love is essential; gregariousness is optional. Cherish your nearest and dearest. Work with colleagues you like and respect. Scan new acquaintances for those who might fall into the former categories or whose company you enjoy for its own sake. And don't worry about socializing with everyone else. Relationships make everyone happier, introverts included, but think quality over quantity.

Now that you're an adult, you might still feel a pang of guilt when you decline a dinner invitation in favor of a good book. Or maybe you like to eat alone in restaurants and could do without the pitying looks from fellow diners. Or you're told that you're "in your head too much", a phrase that's often deployed against the quiet and cerebral. Or maybe there's another word for such people: thinkers.

...remember the dangers of the New Groupthink. If it's creativity you're after, ask your employees to solve problems alone before sharing their ideas. If you want the wisdom of the crowd, gather it electronically, or in writing, and make sure people can't see each other's ideas until everyone has had a chance to contribute.
