/lit/ - Literature

I want to write, but I'm flooded by so many half-assed ideas I don't know which to stick with and flesh out. As soon as I try to decide on one in particular, I only end up drifting away into another, and at the end of the day nothing gets done. Granted, they slowly evolve even when I don't work on them, but at such a pace that it might as well not happen. And it doesn't help that it takes next to nothing for me to skip from one story to another. I can see a random object and think, "Wow, that's pretty, I want that in my story," and suddenly I'm trying to find an excuse as to why I'm adding a new character so that she can wear a particular pair of heels I find hot. I'm just so scatterbrained it's not even funny. Pic related, me each and every time I think of something new and it seems like a big revelation and I decide to skip to another story for no reason whatsofuckingever.
If anyone has some actual advice for this, I'd really appreciate it.
