This is a surreal post. I am not sure if I will be able to make my thoughts clear to you. But I am going to try.
I have always felt like that, I think, but it has been getting stronger lately. It is as if I were merely an observer, watching society from a distance without getting too involved in it.
For example, while I do have a few friends, I never really feel like I am part of their group; it feels more like I am just tagging along, without really caring about them. I was never really interested in people, although I like to have somebody to show my antics to.
The same applies to studying: while my classmates consider me "brilliant, but lazy", I am simply too uninterested to care. I think I could achieve something worthy of note if I could focus, but I lose interest in anything after some time.
Recently, I lost my interest in swimming, which used to be one of the few guaranteed ways of keeping me entertained ever since I was a kid. I also concluded that I have too many flaws and little desire to change, rendering me completely unfit for relationships. Which is not that much of a problem, since I am not as interested in romantic relationships as I used to be (not that I ever tried).
The only things I still care about are work and video games. I am very interested in finding a good job after my current internship ends and my superiors consider me a reliable and hard-working individual. I am also very interested in adventuring (for example, exploring, scuba diving and piloting aircraft), although I have never done any of those things: I do not have the money for that. In fact, my unrealistic desire for adventure is precisely what drives me to my vague goal of becoming rich and living away from society.
In other words, I am living in a world of my own, where no one else is allowed in. And I am only using the "real world" to make my "private world" a reality, which means I am not fully capable of experiencing what our (or should I say "your"?) society has to offer. And that is terrible (or not).
As for the point of this post: I am still trying to figure that out.
