What I keep thinking is that "making X primarily for others" is intended to mean "other people are the driving influence on what kind of X you produce", in a sense that you lose your individuality by creating only what other people want.

However, I often think it's intended to mean "producing X so that other people can consume X, regardless of what results."

And I have frequently heard that it means "producing X so that other people can critique your work and tell you how to improve."

These interpretations seem to be at odds. I've had instructors in creative bootcamps tell me that the difference between the strugglers and the greats was that the greats released their work to the public, got critique on what to improve, and integrated that advice into their next work. In their minds, remaining solitary means you won't get that critique and will always lag behind someone who communicates with others to find better ideas and improve on their own.

So it really isn't as cut-and-dry as "screaming into the void is better", in terms of how I personally frame the distinction.

At an overarching level, my primary wish in life is to leave something in the world that serves as an artifact of what kind of person I was. Maybe this wish is at fault and I ought to get a better wish instead, or I'll be destroying my drive for creation at every turn. But in the present, this is how I honestly feel.

Put another way, if I were to write a thousand pages worth of novels over the course of my life, never releasing any of it, and just before I was about to kick the bucket I were to pour a bucket of gasoline on the entire pile of paper and burn it to ashes, I would probably feel the worst I'd ever felt about myself up to that point. I would have destroyed a significant product of my existence, and in a sense, destroyed a part of myself.

So maybe this way of thinking is flawed, and this clearly indicates that I am overly attached to my work, and perhaps to the idea of social acceptance as well. But this is why I cannot force myself to create if I know nobody is ever going to share a space with my work. Why would I be doing this if I was only going to keep all of it to myself?

And this doesn't even have much to do with the solitude that creating something necessitates - I am capable of weathering the darkest, loneliest storms alone, but only if I believe that there is someone at the end of the tunnel who would be able to see what came out of it all. Otherwise, the entire effort is nothing but toil with no sense of reward.
