Writer’s block is usually a result of your internal editor being adjusted louder than your internal creator. When your internal editor says “not good enough” too often or too loudly, preventing you from getting the words in your head onto the page, tell your internal editor, “It’s a good start. I can change it later if I need to.” Just keep repeating that until it’s louder and more persistent than your internal editor. I also recommend reading Anne Lamott’s Bird by Bird (O’Neill Library PN147 .L315 1994).
