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.'
Don't think of introversion as something that needs to be cured...Spend your free the way you like, not the way you think you're supposed to.
Any time people come together in a meeting, we're not necessarily getting the best ideas; we're just getting the ideas of the best talkers.
Men are more likely to be introverted than women are, but it's really very slight. But the real difference I think is in how it plays out, how it relates to cultural stereotypes.
What's interesting is relative levels of introversion tend to stay the same. If you went back to your reunion from school, you would probably find that if you ranked everyone in your class into terms of levels of introversion and extroversion you'd still be the same rank.
Some introverts are perfectly comfortable with public speaking; I'm not one of them.
