Ideas are work.
More than once I have started down the path of a story idea and come up against major obstacles. “Ugh, that’s too trope-y,” or “No, that reminds me too much of [other book].” And you know what it’s tempting to do when you hit a big picture snag like that? Write the whole idea off. Because, who wants to waste time developing something problematic at its very foundation?
But here’s the thing.
“Obstacles” can be gotten round. “Problems” can be solved. X has already been done before? Big whoop. What’s new? (Certainly not the grievance that it’s all been done before.) Y is a hackneyed cliché that you’ll eat paste and die before subscribing to? Clichés are as old as time raised your ancestors, but they still managed to invent things. So do we.
My point is this: when you recognize a problem with an idea, that is not just cause for casting the idea away. That is cause for putting the problem under your microscope, studying it, and accepting it as your first creative challenge.
If the core of your idea, if the thing that first sparked it is original and raw and excites you, it is worth breaking rocks for.
What is the spark/heart/core of your idea? The spark is often the first thing about the idea that came to you. It could be a concept, a scene, a phrase, a spoken line. It is the thing from which everything else unfolds. It is the one essential, non-negotiable bone of your story (And here is what has been a recent revelation for me: Especially in the planning stages, most of your story is negotiable). If you can isolate the spark, you can carry it through different permutations until you find the pieces it fits with.
That’s not to say you mightn’t need to put an idea down for a while and let it sit, get some distance and perspective—but if you have your spark, and you can pinpoint your concerns—even the big picture ones—you can creative your way around them. Give them a twist. Come up with something else. Try new pieces on, cast old ones away or rearrange them.
But if the spark of your story grabs you, for fiction’s sake, don’t throw it out!
