It really depends on the what the declaration is, and how it’s made.
If it’s “I really don’t want to leave but I can’t stay here unless these issues are resolved”, then it’s a discussion. If it’s “the moderators suck”, then ahaha good luck to you. If it’s “I can’t stay here if Janie Sue is here”, then that’s between you and Janie Sue, resolve it over PM.
If it’s “I am an invaluable member of this community and I am punishing (any or all of you) by withdrawing my splendid visage from your presence” then seriously, don’t let the door hit your ass on the way out.
Perhaps. There are more kinds of excellence than I think even good artists often realise, however. I was a woodwinds player myself, but I was certainly never going to be first chair anywhere. I did have a better-than-average sense of rhythm and phrasing, and I think that shows up in my compositions. In this area, at the tender age of 63, I am still growing. It’s a suitable application for my strengths as a musician. Will I gain any recognition in my lifetime or beyond? Who knows? It’s not really important.
Mind you, I never gave up the day job either, and that might have been a mistake on my part.
What’s the situation with the trembling hands, if you mind my asking? RSI?
Edit: Oh, and I recently picked up an Akai EWI-USB. It’s a real pleasure to play. Highly recommended.
2nd Edit: I have just seen the “Ask me anything” thread. I’ll catch up there.
