Yeah! So - I will caveat, outlining is highly individualized, and I know people who outline in both far more and far less detail than I do, but this is what works for me: https://twitter.com/mesmey/status/1319871609767890946

I tend to outline by scene. Each scene is a bullet point that has the major beats underneath it, some of which may make their way explicitly into the scene and some of which may just be background notes. I'm going to use trash magician as an example again:

Some outline scenes have snippets of dialogue. Sometime this makes it into the final version unchanged, but more often this it's just a starting point, an idea that I want to get across:

And there's point 3b, which is - IGNORE THE FUCKING OUTLINE when you need to. For example, the final scene of trash magician originally took place in yibo's kitchen, not the vacation home:

The bones of those notes made it through, but the final implementation looked significantly different. Finally, when I've got the scenes I think I want in the order I think I want them, I put them in a table which helps me conceptualize the overall flow:

Usually I've started writing at this point, and from there it's a matter of outrunning my own anxieties haha. The outline helps me feel like I'm making progress, but I tend to write them loosely enough that I still feel like I'm discovering the story as it's being written.

I also tend to add/clarify scenes as I go - the final scene count is always larger than the initial estimate, as I figure out what needs to happen, or what tropes/ideas I'd like to explore along the way.

Outlining helps me organize my thoughts, but I never feel beholden to it if I get to a point where it feels like the story needs to go in a different direction. I will say, though, that it is incredibly satisfying to cross sections off then they're complete. :D
