The other day as I finished a writing session I commented to The Engineer that I had cut 200 words. He replied "I know I'm new to the whole writing thing but isn't that counterproductive?" First, he's an engineer, it's all about cost/value effort/progress. Second, he thinks he's funny. "Now that you're done writing are you going to unwrite it until there are no words left? I believe those kinds of novels are called reams of paper but hey, at least you'll be able to tell the agent it's perfectly grammatically correct.
Even with no words I doubt I could make it grammatically correct.
The thing is that there are a lot of aspects of writing that could make us feel as if we were taking a step back. A shrinking word count, Or growing word count if we're trying to cut the size, starting a new draft, getting feedback and having to write that one scene yet again.
As writerjen said on her blog,
"If I'm on the right road, it doesn't matter how rocky it is; I know I'll get there. All I have to do is deal with each pothole and hairpin turn as it comes."
Keep moving, keep following the path and we'll reach the end eventually.
