But as well as turning up at the page, we need to turn up to the world of writing. We need to get involved. Go to conferences, subscribe to magazines like Mslexia or Writers Forum, join writing groups, follow writers on Twitter and Facebook, read writing blogs, join writing societies, attend writing classes, subscribe to daily publishing news digests like book2book.com or The Bookseller so you're up to date with the world of publishing.
After a while you'll become recognised, then accepted as part of the writing world yourself. Perhaps there are some people who don't need to get involved to get published, who can loll around in some ivory tower and magically land a wonderful publishing deal. Personally, I've yet to meet them, although I have met depressing numbers of people who seem to think it's enough for them to have written a novel, they don't need to bother with getting involved with the publishing world. Then they get bitter when they don't get published, claiming publishing is clique.
In my experience publishing is anything but a clique. It's open to anyone and everyone, but no one is going to push the door open for you. You have to do it yourself. Turn up, and get published.
