This - "Many introverts feel there’s something wrong with them, and try to pass as extroverts. But whenever you try to pass as something you’re not, you lose a part of yourself along the way."

In fact, damn near all this.  More at the link.

The Power of Introverts: A Manifesto for Quiet Brilliance | LiveScience:

"Introverts prefer quiet, minimally stimulating environments, while extroverts need higher levels of stimulation to feel their best. Stimulation comes in all forms – social stimulation, but also lights, noise, and so on... So an introvert is more likely to enjoy a quiet glass of wine with a close friend than a loud, raucous party full of strangers.

It’s also important to understand that introversion is different from shyness. Shyness is the fear of negative judgment, while introversion is simply the preference for less stimulation. Shyness is inherently uncomfortable; introversion is not. The traits do overlap, though psychologists debate to what degree.

Cook: You argue that our culture has an extroversion bias. Can you explain what you mean?

Cain: 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.” Our schools, workplaces, and religious institutions are designed for extroverts. Introverts are to extroverts what American women were to men in the 1950s -- second-class citizens with gigantic amounts of untapped talent...

Cook: How does this cultural inclination affect introverts?

Cain: Many introverts feel there’s something wrong with them, and try to pass as extroverts. But whenever you try to pass as something you’re not, you lose a part of yourself along the way. You especially lose a sense of how to spend your time. Introverts are constantly going to parties and such when they’d really prefer to be home reading, studying, inventing, meditating, designing, thinking, cooking…or any number of other quiet and worthwhile activities.

According to the latest research, one third to one half of us are introverts – that’s one out of every two or three people you know. But you’d never guess that, right? That’s because introverts learn from an early age to act like pretend-extroverts.

Cook: Is this just a problem for introverts, or do you feel it hurts the country as a whole?

Cain: It’s never a good idea to organize society in a way that depletes the energy of half the population...

Cook: Are you an introvert?

Cain: Yes. People sometimes seem surprised when I say this, because I’m a pretty friendly person. This is one of the greatest misconceptions about introversion. We are not anti-social; we’re differently social. I can’t live without my family and close friends, but I also crave solitude. I feel incredibly lucky that my work as a writer affords me hours a day alone with my laptop. I also have a lot of other introvert characteristics, like thinking before I speak, disliking conflict, and concentrating easily.

Introversion has its annoying qualities, too, of course. For example, I’ve never given a speech without being terrified first, even though I’ve given many. (Some introverts are perfectly comfortable with public speaking, but stage fright afflicts us in disproportionate numbers...)"
