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.
Opposites attract, and I think temperament is so fundamental that you end up craving someone of the opposite temperament to complete you.
To some extent, we've always had an admiration for extroversion in our culture. But the extrovert ideal really came to play at the turn of the 20th century when we had the rise of big business.
In our society, the ideal self is bold, gregarious, and comfortable in the spotlight. We like to think that we value individuality, but mostly we admire the type of individual who's comfortable 'putting himself out there.'
I get a lot of letters from introverts asking how they can meet people. The key is to make sure that you are doing things you enjoy.
