Most of us have a basic understanding of what the term ‘extroversion’ means. We often identify an extrovert by their friendly and approachable nature, as well as jovial personality. There is, however, much more to gregarious people than what meets the eye. As humans, it is part of our being to analyse those around us, and infer things about them based upon our observations; that said, it is important to know that there are certain aspects of an individual’s personality that exist, but go unnoticed. These characteristics, feelings, or thoughts are internal, and are thus kept hidden away from the surface.
