The most helpful quality a writer can cultivate is self-confidence – arrogance, if you can manage it. You write to impose yourself on the world, and you have to believe in your own ability when the world shows no sign of agreeing with you. A book isn’t quickly achieved and the road to publication can be strewn with obstacles. It is especially important to be self-confident if you have no contacts and do not know other writers. If you are unpublished you can still say to yourself, “I am a writer.” You should define yourself as such.
