Just got a rejection for my latest manuscript, Cassidy's War. But you know, it's not all that bad. The editor had a lot of great things to say about the submission and only had one problem, but gave me a lot of ideas on how to fix it. And although fixing that problem will require a whole lot of rewriting, I've decided I'm going to do it.
The suggestions will make the manuscript better, so why not put a little more work into an already good manuscript to make it great!
For now, I'll put it aside until I finish up some other projects, then I'll tackle it head on. If you're serious about writing you have to learn to write and revise, revise, revise.
