A lot of writers have rules. Most of these rules apply to the stories, but there are a few that pertain to the art and craft of writing. One of these "rules" is that all first drafts suck. Anne Lamott makes this claim. I think it's bullshit. Why do writers tell new writers this? To make them revise and revisit their work. The very least a writer can do is check for spelling errors and gross grammatical mistakes and fix them before asking anyone to check the draft. This isn't easy, because a sentence that you think is perfectly fine, probably a bit long, but you don't want to break it up into smaller 'Dick and Jane' sentences, is a comma splice error. You can't please every grammar maven, but you can fix most of the big mistakes with ease. No, first drafts are works of genius. There's only one reason to put words to an idea: because it's a genius idea.
There is a catch. Some works of genius keep their genius quality for centuries, others not so much. Chances are your first draft will not retain that quality, the genius aspect of the story doesn't stand up to the test of time, probably for an hour or two, but that's it. That's the art of writing: putting bits of genius on the page.
The craft comes later. Checking grammar and spelling and making sure a girl you describe as having green eyes doesn't have blue eyes later (unless that's vital to the story) are drudgery. Painters have to clean their brushes, sculptors have to sharpen chisels. Writers have to spell check. No, the craft of writing involves taking the genius first draft and giving the genius more momentum, so eventually the obvious genius quality will last until an editor writes you a check for the piece.
Do art and craft mix? All the time. Find the joy in moving phrases to their proper places in your manuscript. Treat your work like poetry, because it is a work of genius.
