Great bit of writing intelligence from one of my favorite radio writers, Nancy Updike.
Save earlier drafts/make an OUTS page… As soon as I open a page to start a story, I open another page and label it ‘OUTS.’ Anything I cut from the story, I paste into the outs page. Any time I start making major revisions in the script, I save it as a new version. It’s hard to resist having a sort of Enlightenment view of whatever you’re working on-it’s getting better and better all the time!-but sometimes the way you phrased some bit the first time was best. And sometimes not. With the earlier versions saved, you can compare and choose.
The entire article is excellent. You can check it out at: Transom » Nancy Updike
