How important is self-expression to you? Do you have any clue why you have your level of need for self-expression?
I use the term "self expression" broadly - it can come from things ranging from voicing opinions, to talking about things you experience with close friends, to engaging in creative acts that are shared with other people, to giving speeches, etc.
I've always felt like I have a much lower need to express myself relative to other people, and have long been baffled by other people's seemingly higher needs for it. Often people think that I'm "just shy" when I don't talk about myself or share my opinions or not engage in creative outlets (I only notice this because a lot of people in my life are artists), but it's often out of an absence of any internal need or desire to share anything about myself. Pure indifference, really. It's like I often don't see the point. I'm not entirely sure why, myself, other than that I have a simple absence of a compulsion for it.
I want to understand the differences in people's needs to express themselves, and why some people have higher or lesser needs for it than others.
