This might actually be a blessing. Several members of my critique group suggested back in May a few changes that the first line restricted considerably. So upon receiving the rejection, I took to revision. The biggest change was from third person to first, which facilitated a few other changes.
I hope to bring the revised version to the group meeting tonight, and then figure out where to submit it to next.
I am a big proponent of writing to ‘constraints.’ I believe the constraint helps to jumpstart the creative juices. However, one must be able to leave the original constraint behind when appropriate.
