I honestly think we’re all saying the same thing now. EXCEPT that we haven’t really addressed how best to use this technique. It might be worth watching the latest Conflict Corner where the analogy of a puppet was first mentioned. The characters are puppets, the story world is the cool little stage. And finding these true sources of conflict is like figuring out the puppeteer’s hand that is driving the story. What’s behind the puppets.
With that analogy in mind, I would suggest that for most writers it’s not very useful to start with the puppeteer’s hand. Who cares about a puppeteer’s hand without the puppet? I would MUCH rather start with the puppets themselves, the architecture of the stage, make those cool and interesting. Only then do I start to care about the forces driving the puppets.
Putting away the analogy, something like “Should I make progress toward what I want if it destroys my present?” is almost meaningless without characters and storytelling context. I don’t care about it one whit. But look at it in the light of Star Wars (a farm boy who wants to be a freedom fighter), or some other cool idea (a child discovers that the geometrical arrangement of the benches in the park near his house is the key to holding back the apocalypse), and suddenly it starts to mean something.
I think you’ll end up with much better sources of conflict (puppeteer’s hands) by starting with the storytelling context (the puppets). That’s what will what make everything meaningful to you, and you’ll come up with meaningful sources of conflict naturally, without having to try.
But with all that said, the Conflict Corner process is eminently useful for a later stage in the process. When you find one of the puppets is not pulling his weight, you can figure out if the hand underneath is timid or weak, and use the process to give it strength and passion. And the point of Conflict Corner is to get better at doing this.
Of course, all this is just how I see it working based on the type of writer I am. For others YMMV. (I know some people like to start with a theme/premise as their story idea, which seems insane to me! But to each his own, and if that’s the case you would certainly approach things differently.)
