Blake, if you have a story worked out in advance, then I suggest you continue writing it out in draft form; you can return and expand or inprove your draft. Are you simply stuck for a plot, or are you *** off with your poor literary quality? Plot? Maybe sit with a pencil and a notebook and work out the rough lines of what happens. Quality? If you can see it's not good, then you are halfway there because you are able to see that it's not right and you can improve it by editing until you can see that it's good.
