November is a good month to submit finished manuscripts to publishers, because everyone else is too busy writing.
But then December comes, and your submissions get lost among the sea of NaNoWriMo people who think their month-old manuscript is ready for prime time.
Weird how landing a publisher is so dependent on timing.
Lol. Well, you might be right. But anyway, I certainly wouldn't submit my manuscript right after writing it, and certainly not the month after!
Timing is important, but from my research the quality of your manuscript and sheer persistence are what really get you published. You just have to be really okay with rejection.
