"Whatever you're writing, write the first draft with the attitude that if you go back and edit anything, even the placement of a single comma, the draft will die and you'll never get it back. When you're done, you'll love some of it and hate other parts. That's OK, because nobody has to see it but you. Just get that first draft out — it's where you find the story and your core message. Then you can go back and edit before you send it out."
