Party of One: The Loners' Manifesto
They say that only about 15 to 20% of the population is introverted and that extroverts just can't seem to wrap their minds around the concept of alone-time. Introverts have been described as people who need alone-time or "me-time" to recharge. Extroverts, on the other hand, are like solar panels that must be pointed towards other people in order to feel charged. Don't let the subtitle throw you. introverts are not always loners and vice versa. The word loner also seems to carry a negative connotation at times as well, "crazed loner" for example. If you're an Introvert, this book will sing to you. If you're an Extrovert, it will help you understand the antithesis of your personality type.
