I don’t believe you are a failure as a writer just because your first book was not accepted. Self-publish it. Write another. Then another. If writing is your true desire, you’ve got to keep doing it, because it’s your life and your legacy. What about the artists who never sold a painting in their lifetime? It doesn’t make them any less gifted as artists. You have a great voice and your own unique story to tell. Don’t give up. Keep on trying, just like the rest of us. You have an audience waiting for you to speak — don’t disappoint them. Go for it, Zach!
