" Is there a particular trick to rewriting? Yes! Only rewrite what doesn’t work, and leave the rest alone. This often means working against the temptation to do more and more. It means not getting carried away by new and different ideas that are exciting but don’t fix your script’s problems. It means following suggestions that are designed to get the script on track, not off. It means holding back on a new creative stamp because the writer’s original creative stamp is “just fine, thank you.” If it ain’t broke, don’t fix it! And if it is broke, do something! "
