Fred Himebaugh lists "four freedoms" for composers, especially composers who are "stuck" . For the sake of completeness, I'll note that A. C. Douglas singles out two of them for endorsement: Freedom from the Masterpiece Syndrome and freedom from the quest for complexity, which are, I believe related, in that they can make the composer so self-conscious that he or she can't even decide how to spell a given note, for fear of something or other. In fact "Freedom from Self-Consciousness" is an umbrella over all of these concerns.
I would add a corollary, or flip side to the freedom from the quest for complexity: Freedom from the Ache for Accessibility. One never knows what an audience will like or dislike at any given time, so tailoring your music to try to make it "likeable" is a fool's errand, and more than a little condescending.
Why "condescending"? If you think you have to change your music (or your art in general) so that the audience will "like" or "get it", then you think the audience can't "get" what you are after in the first place. Write what you hear and what you feel. If your talent and skill are up to your inspiration there will be an audience for it.
Now, as for finding and cultivating that audience . . .
