I don't want... anything.
Then why are you making this post?
If you really want nothing, stop doing. Sit. Wait.
If after 100 hours of sitting doing nothing, you still want nothing, I'll believe you. Don't think of this as a challenge. Wanting to "prove something" would be wanting something. If you truly want nothing, then stop doing. Be.
I'd usually agree with you but right now, you're just being needlessly obtuse. The subtext here, I can deduce is that, Helmacon hasn't figured out what he really wants at all, while others have, and he wants to figure out at least the "why" of not being able to feel strong desires for anything.
More on the topic,
It's hard to say if I used to be that person, because
I still have not figured out what I really want. I have base objectives: get rich, get a "good" life, help others, etc. but is that what I really want? Those goals were merely put into my psyche because everyone else is chasing for that dream.
I once had dreams of wanting to pursue a meaningful relationship, but with my mindset right now, is that what I really want? Or do I merely want to use said meaningful relationship as a crutch; to discover myself so on and so forth as to what I really want to do.
I liked listening to music, and I still consider myself a musician. But I have since stopped doing anything, such as playing my instrument of choice: the piano; or trying to learn more about FL Studio. Despite that aforementioned thing, I feel no real need to pursue said hobby, and put it in the backburner. I then ask myself, is this what I really want?
And so I am left with a lot of blank questions, to which I do not know the real answer.
I did, however, discover that if you keep digging into things long enough, you might discover a small spark of passion, which may be enough to give you a real, meaningful goal. I look at a lot of things, and discover that goals, or at least the ones most meaningful, are never forced out or given by other people. It's what people decide for themselves.
You need to discover what it means to be alive, on your own, with your own mind defining its thesaurus description itself.
For me, even with the above lack of true goals issue I mentioned, finding new goals to keep is more than enough for me to keep pushing onwards. And you will have to decide on your own if it's a goal worth keeping or not.
