If you write a hundred short stories and they're all bad, that doesn't mean you've failed. You fail only if you stop writing. I've written about two thousand short stories; I've only published about three hundred and I feel I'm still learning. Any man who keeps working is not a failure. He may not be a great writer, but if he applies the old-fashioned virtues of hard, consistent labor, he'll eventually make some kind of a career for himself as a writer.
