George Eliot wrote always with a sense of failure and doom. Nabokov was fully aware of his greatness. I think you must be somewhat aware. Not wishing for a response here, I’ll just say that talent at a certain level carries the obligation to write, especially if it’s not fading. We’re all at our full powers only so long, but some writers soar well into “retirement” years. I’m afraid you’re still on obligation status.?
