>>2312483Totally up to you, but the one I've stuck with is starting with a skeleton and build it from there. First write down the ideas you have in whatever way is comfortable, then start building the skeleton for the plot. The skeleton is a list of very short bullet points outlining the story from start to end (you just have to force it, once you've started writing down several bullet points more ideas will come) and do this until you have a whole plot from start to end in bullet points. My bullet points look like this: "This and this character meet for the first time", nothing more complicated. Doesn't matter how many or few there are, as long as you have a start and an end.
Next, you start filling in details underneath each bullet point, these are now starting to form the actual chapters of your story. You're now done with the foundations of your skeleton and can move on to flesh out your story in full. You can do this by building on the bullet points and texts even further, or put it to the side and use it as reference as you now write a full rundown chapter by chapter from start to end. Rearrange and add stuff as you please, by now you'll know your story well enough to trust your instincts. With every chapter outlined in detail, all you have to do is just write the story itself. I also like to keep little notes throughout my chapters (with a different text colour) where I write down things to keep in mind such as character themes or foreshadowing that must be included if you have plot twists and the like coming later in the story, so you don't forget to include this while writing the story. I think a lot of writers do a variation of this, but for me it helps to think "skeleton, foundation, meat" just to keep it simple.
