I had a great idea

I had a great idea yesterday morning for a short story. I even had place to try to pitch it because it’s so commercially viable and topical, there was a place to pitch it. Not just any place, but a place run by someone whose work I’ve followed for years and whose work I admire. I even started writing the pitch. I got through the opening and then I realized I wasn’t taking it seriously enough and since I wasn’t taking it seriously enough, I shouldn’t pitch it. I should let the idea flare and die.
