So, I've been attacking an old short story of mine slated for publishing soon. The editor needs it knocked down to 10,000 from its current 11, 600 word count. This is the kind of thing I actually love doing. Particularly as this story was originally written 3 years, and I have learned all sorts of things about word economy since then.
On just the first read-through, I knocked out almost 800 words. The second 800 will come from consolidating and re-shifting action, and removing some more excess dialogue -- all of which it sorely needs.
I love having this opportunity! Otherwise, I would have cringed at the thought of anybody ever reading it!
