I wish to express that art is self-indulgence, and that one shouldn't expect others to care about your art. I need to sum up this idea in a curt phrase suitable for a point in a list. The phrase I've got right now is
Art is self-indulgence; don't expect others to care about yours.
or
Art is self-indulgence; don't expect others to care.
I'm afraid this isn't clear. How can I rephrase this so it is unambiguous.
