“The way these creative individuals confront life suggests that it is possible to be both extroverted and introverted at the same time. In fact, expressing the full range from inner- to outer-directedness might be the normal way of being human. What is abnormal is to get boxed in at one of the ends of this continuum, and experience life only as a gregarious, or only as a solitary being.”
