There speaks a true writer. But it depends on how much you want to be published. At the basis of every novel acceptance is a story, and the story has to be readable, and it has to be enjoyed by the readers.
You're absolutely right, Zolah, in that there is no formula for novel writing. There are certain accepted standards, but the huge variety of books out there show that you can write about almost anything, and in almost any style.
But yeah, I'd hate to spend a year or six months or however long producing something I didn't believe in. But the problem here is that it's so early in the story, and as we all know, if you can get someone to read what you've written, many opinions are formed in the first page or two. If there's something that looks 'clunky', they might not bother reading on.
Perhaps another solution is to write what you want to, but when you submit it off, 'sanitize' it a little, make it a little more acceptable. Then, when you get your contract and your huge advance, show them the real beginning in your first edit and see what they say.
See, Zolah? That didn't hurt at all, did it?
