We writers or artists, at least some of us, push ourselves as far as we can, coming to a point where we no longer know if a piece is any good or not, only that we’ve done everything in its pursuit that we possibly can at this period in our life.
Either it gets published or whatever as is or gets pushed aside, maybe to be picked up later and reworked, maybe to go in the trash. Or maybe Death intervenes.
