Here is the number one thing you must do to be a writer. Sit at your computer/typewriter, place your fingers on the keys and start writing. Keep writing until it starts making sense. Then write some more until it looks like it is going somewhere. Then write until it feels like it is complete. Stop writing. Start editing. Start writing the edited version. Keep writing until you are satisfied. Stop writing. Go away for a month. Read what you wrote. Does it look good? No. Start editing... Yes. Format the manuscript until it meets a publishers standard. Send it in. Any questions?
