I knew very early on that I was an introvert. Of course I didn’t know that’s what it was called back then; I doubt many people did. As a kid, I was simply referred to as “quiet” or “shy”. I was just as happy being alone in my room with a book as I was outside playing with my friends. Shy? You bet; painfully so at times, especially around girls. (I can’t remember the last girlfriend I had that didn’t have to make the first move. And that includes my current wife). But as Susan Cain writes in her book, “Quiet: The Power of Introverts in a World That Can’t Stop Talking“, shy and introverted are not necessarily the same, and it is important that we recognize the distinctions.
