Over the course of a project, I keep all of my revisions on my computer. Whether it's a TV or radio script, a list of headlines or body copy, I begin with a file like "TVscripts01.doc" which is usually followed by "TVscripts02.doc" after an internal review and "TVscripts03.doc" after that.
My point in telling you this isn't to encourage you keep your old drafts (I rarely revisit my own). It's to say that by the time a project is approved and on its way to production, it's usually labeled "TVscripts17.doc" or "Headlines15.doc."
That's not an exaggeration. It's just another reason to not fall desperately in love with the first ideas you have. There will always be something better.
