I have dozens, maybe even hundreds of partial ideas and story prompts. Several jump out at me and I think, "That would be cool." But that's it. No flood of subsequent ideas. Just a desire to write a story that would be cool. It’s like… I'm just not feeling it. But I want to write something.
It's not writer's block. It’s just writer's meh.
I need something to give me that push off the edge. The thing that makes me stop what I'm doing and say, "Holy shit, what if that happened?!" That's the best thing, when you have so many ideas and plans and you can’t write it down fast enough. It's a rare thing.
