When you’re writing your first draft, I strongly advise you not to edit. Let your ideas flow. If you try to edit now, you may never finish your novel. Or worse yet, you’ll stifle your creativity.
There is another voice, one that may or not be your inner editor. The one that tells you this isn’t any good. Why on earth did you think you could be a writer? You should just give up before anyone discovers you can’t really write.
These, my friends, are the voice of the enemy. Do not believe his lies.
