This document provides a self-assessment quiz to determine if a person is an introvert. It lists 23 statements about preferences and tendencies, and instructs the reader to respond "Yes" or "No" to each one depending on how well it describes them. Some examples of the statements include preferring one-on-one conversations over group activities, feeling drained after being around many people, and enjoying solitude. It concludes by saying the more "Yes" responses one has, the more inclined they are toward introversion. The rest of the document provides contact information for professional development training programs.
