Susan Cain is a writer and researcher, most recently focusing on introversion. In her book, "Quiet: The Power of Introverts in a World that Can't Stop Talking" as well as her TED Talk, Cain discusses how introversion is an asset in a culture that extols an extrovert ideal. Introversion has been inaccurately believed to be a term describing shy, socially awkward people. In reality, introverted people respond to external stimulation differently than extroverted people (who actually respond differently to internal stimulation). The fact is that the majority of us are somewhere on the scale between introversion and extroversion. The key is to figure out how you process information best, how you communicate best, and how you FEEL best and go from there. A bit of introspection -- and even some sessions with a therapist -- can be incredibly helpful in figuring out your healthiest, most successful self.
