I am rewriting parts of my novel one more time, especially the early parts. I hope rewrites on the first few chapters will increase my chances of finding an agent or publisher. They typically require submissions to include a sample of the first 1-5 chapters, so rewriting these to make them better might increase my chances on any given submission. I expect these rewrites to be finished by the end of the labor day long weekend, after which time I'll resume submitting.
