Keep in mind that introversion and extroversion are not all-or-nothing traits. Imagine a spectrum with introversion on one end and extroversion on the other. Everyone lands somewhere on that spectrum, with some falling closer to the introverted end and others nearer the extroverted end. Nobody is a pure introvert or extrovert. “Such a person would be in the lunatic asylum,” wrote Carl Jung, the famous Swiss psychologist who first coined the term introvert. In other words, we all act “extroverted” in some situations and “introverted” in others.
