All ideas are worth it
About five years ago--maybe more--I had an idea. It was an idea that I couldn't figure out for the life of me, but it was an idea.
This idea kept rattling around in my head. It would show up every few months as a scene that I couldn't play out. I didn't know who the characters were, how to get them to the scene or what to do after the scene.
It was just a scene.
Cut to now. The scene is almost non-existent, but the manuscript is finished. 70,000 words and change.
At one time, it was just an idea.
