I've been writing a novel for about 6 or 7 years now (I've lost track). The idea has changed over those years and other ideas have come along which I have incorporated and some ideas have been put aside for later projects. Ha! I have started another novel involving the same character, and then gone back to my original idea. I am determined that they will both be written, as well as many other things I hope. I have completed a short story which I am really proud of. I am mainly proud of the fact that I completed it. I entered it in to a short story competition this year but it didn't win, not that I at all expected it would, but you know, we all have to dream.
So I believe I am a writer. I have written a short story. Draft zero (see my first post), first polishing, final draft, submission to a competition. That's writing. But so is writing a novel or a short story that is never published. If you've done this, guess what? You're a writer. If you've written a draft of something, you're a writer. If you've written a few thousand words of a burgeoning novel, you're a writer. If you've written a few pages, you're a writer. If you've written a few words, you're a writer. If you're writing anything, you're a writer.
Just keep at it.
I owe a debt of gratitude, again, to Jason Arnopp for this post. He wrote a blog post along similar lines which you can see below.Also to Johanna Nield for highlighting it. You can also link to Johanna's blog below, which is well worth a look.
