While these will sound familiar, I want to call out the first one: Write your 1st draft as fast as possible. This works on two levels: 1) you keep the momentum going while you're still excited, and 2) you counter the "you can't edit what you haven't written" dilemma, aka writer's block, aka procrastination.
