my work and art are more important than me
Imagine art critics studying your art - they would be asking what was your history, context, what happened to you and what was going through your head that made you do this. It's always about you, even - maybe especially, considering that defeating one's ego is still noteworthy - if you don't want it to be about you.
Making art that's not about the artist is reserved to LLM... At least for now.
Second, the idea of "your work and art are an expression of you" is dangerously self-centered, in that it can limit your growth by pushing you conform to acceptance over aspiration.
