Psychologist Robert Maurer notes, “You publish your first novel, does that make fear go away? No. So your skill at being able to nourish yourself and give yourself permission to make mistakes and learn from them is your single greatest attribute as an artist and as a human being.”
He also declares, “Fear is good. We view fear as a disease. It’s not a disease.”
Fear is excitement. You're excited about your writing, aren't you? :-)
