It’s OK to be an introvert. In fact, it’s desirable.
I grew up in a generation, time, and place in which it wasn’t cool to be introverted. In fact, any research on introversion/extroversion never hit the news stand in my world.
Introverts were “bookworms” or “wallflowers” or “snobs.” Not necessarily so.
I don’t apologize for my introversion anymore.
