When you spend most of your time in the “inner” world. Spending a lot of time thinking. You’re in your own head. Sometimes it’s reflecting on or reliving the past. Sometimes it’s spending time in the future, considering how things will work out, worrying about what might be, making a plan. Sometimes it’s not being present in the present because of being lost in thought. It’s trying to figure out what just happened. Introversion is telling stories to yourself about what makes the most sense. Introversion is daydreaming. Introversion is curiosity. Introversion is liking ideas, concepts, and the abstract. Playing with thoughts. Trying to solve mysteries, identify patterns. Trying to find meaning from what you see. The abstractness of the inner world and thinking to think is not overwhelming, tiring, stressful or frustrating. In fact it’s invigorating and energizing because it provides a sense of control and awareness, and a reward for when “figuring” things out.
