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.

I use a lot of old-fashioned expressions.

Solve problems, make art, think deeply.

I think the shyness one feels in childhood is often overcome with time. There are children who hide behind their parents' legs, but you don't see grown-ups hiding behind people. It just doesn't happen. I mean, not that often. People develop social skills over time.

In a way, education by its nature favours the extrovert because you are taking kids and putting them into a big classroom, which is automatically going to be a high-stimulation environment. Probably the best way of teaching in general is one on one, but that's not something everyone can afford.

All personality traits have their good side and their bad side. But for a long time, we've seen introversion only through its negative side and extroversion mostly through its positive side.

Another study, of 38,000 knowledge workers across different sectors, found that the simple act of being interrupted is one of the biggest barriers to productivity. Even multitasking, that prized feat of modern-day office warriors, turns out to be a myth.
