Perks of Being an Introvert

Well I'm an introvert, and although many books have been posted about introverts...
how come none have been about the perks of being one?
I've seen ones where they explain the social anxiety of an introvert but never what's actually great about it

The "chapters" if that's what you want to call them, will be posted when I'm done with them so there will be no pattern with the posting of "chapters"
