Write every day (to keep the world and the characters fresh and alive).
Keep writing – no matter how badly – until you get to the end. Then you can rewrite. And edit. A lot.
As you’ve probably gathered, I’m not a planner. I make collages and soundtracks that ‘feel’ like my book and keep notes in a journal, but to find out what’s going to happen in the story and who the characters are, I need to write it. Which means I need to write straight through a craptastic first draft before I can think about making the story work.
Yeah, it’s not very efficient.
