When you’re an artist, writer, musician. You ASSUME you have something of worth to say. Or at least you HOPE you have something of worth to say. You wouldn’t go to the trouble of spewing your art out to the public in the first place if you didn’t believe that.
But at some point, after pushing your art out to the public for many decades. You start to wonder: “Ya know? Maybe I would have been better off in the long run if I had just kept my damn thoughts to myself.”
