I am an introverted person. I was very happy to read a new book that came out this year Quiet by Susan Cain which is all about introverts. The author has a little set of questions to ask yourself if you are introverted or extroverted. I knew I was an "inny" from the beginning, but the set of questions just confirmed it. You should just read the book if you want to learn all about questions like what makes intro / extroverted people, what are our various strengths and weaknesses, how we introverts can overcome some of our difficulties in life & how parents, teachers, managers, co-workers can best work with us.
