Do you have any ideas about how the end of the story might play out? I don't mean Dramatica ideas, just story ideas. It would probably work best if we tried to come up with stuff that aligns with your subconscious ideas.
e.g. Do you like the idea of them proving the value of the farm? Is that important you, or just a quick thing you threw out because of how it could fit the flipped Problem/Solution storyform?
Note: don't feel bad. I was in the same boat as you until a few days ago -- and I have half my story written! Basically, my storyform seems to be firing on all cylinders so I'm pretty confident in it now, and the OS Problem of Help is very clear. But of the illustrations I had for the Solution of Hinder:
- One is awesome, and ties in with the Change IC's embracing of Hinder too. But for the OS that moment is only one step, there's a lot more to be done to resolve things.
- One was kind of meh, it works but seems kind of trite. "Hinder the badguys", blocking or delaying their incoming attack ship/fleet. It seemed too much in line with the Problem of overzealous Help to be really interesting. I wanted something more at an angle and intersecting, if that makes sense.
But the other day two things happened. First was actually your doing @Lakis, I meant to thank you for it. It was after thinking about your Crucial Element question and my other story where Hinder was the Symptom & MC Crucial, I remembered how much that story made me grok the coolness of Hinder.
The second thing was, I was finally digging into some of my backstory, trying to answer an outstanding question: why were the "goodguys" (Firelion Club) so set on keeping the galactic war secret from the rest of humanity? And I wrote this:
Maybe the original Firelions on Earth (first recruitment) established a Pact, that their agents on Earth would uphold: never to burden the people of Earth with the truth of the Unworlded War.
When I wrote that word burden I got a chill up my spine -- I realized that was where the OS Solution was hidden, like buried treasure. I can still do the "hindering the badguys' fleet" if it makes sense in the story, but the real OS Solution is for the goodguys to change their ways, go against their Pact and finally be willing to burden the rest of humanity with the truth.
So all that to say, I think it's okay to start writing without a full understanding of your OS Solution, maybe pencil something in that isn't quite perfect, and trust that something great will come.
(Sorry for the huge divergence into my own story. I thought it might be useful, but it's pretty long and self-focused. I should probably turn this response into a blog post!)
