Since 2009, I have worked on my Episode I rewrite; in those 8 years, I have written an unknown number of drafts (6 survive). Since June 2014, I have worked on my Episode II rewrite; in those 3+ years, I have written 7+ drafts.
Now — finally now — the revisions, the tinkering, the typographical plastic surgery — DONE. Both scripts are as good as they’ll ever be. I’ll never have to — and never will — return to them again.
