So You Think You Can Write
The big gigantic secret no one ever speaks of in the publishing industry is that very few manuscripts submitted to publishers are actually publishable. We like to believe that all our brilliant tomes clamoring for the attention of editors are so top-notch, editors must agonize over which books to buy, torn between a vast array of great stories.
Ask any editor when was the last time they had too many good manuscripts to choose from. They will probably roll their eyes or laugh maniacally.
The truth, plain and simple, is it's so hard to sell a book because it's so hard to write a sellable one. Add on top of that the task of getting your sellable book in front of an editor or agent whose taste it meshes with, and you have a recipe for how to become an alcoholic.
So why persist? Because it's the persistent ones who sell. Most people look at the odds against selling a book and don't even try. Some people try for a while, can't stand the constant rejection, and then give up. And then there are the weathered few. The ones with the dark circles under their eyes, the file full of rejection letters, and the emergency stash of hard liquor tucked behind the rejection file.
It's almost inevitable that if you keep writing, your writing will improve. If you keep improving, your writing will become sellable. And if you keep submitting, you will eventually find the editor who loves your work enough to buy it.
