oooh, so if we're talking about the kind of writing I do on here, I usually just wait till I one day suddenly think of an idea or fantasy I really like, or one that I've thought of before or never wrote about. and then, I'll decide whether I'm more in the mood to write about it in the style of describing the fantasy to the reader, or describing it as though the reader is an active part of the idea (like, the person I am speaking to and doing those things to). and then, I write it out!
if we're talking about writing outside of this blog, I usually write short stories. and my process for that is making a list of any random, jumbled or even minute ideas I want to include. this list could include themes, concepts, details, names, relationships, minor scenes or even metaphor and literary devices I want to include. once I have all those down, I start creating an actual outline. and in the outline, I'll usually divide it into sections of the story that just fit well (for example, a story I'm currently working on takes place over the course of six days, so the outline is divided into six sections). and then, I'll write out all the scenes, details and events I want to take place underneath the header of each section of the story. then, once that is complete, I'll begin the actual writing process. sometimes, in the writing process itself, I'll realize things I want to change in the course of the story, so I may rearrange the outline or add in and/or remove things. and that's totally okay! also, I know that I can always work on a second draft after the first, and in that second draft, can clean things up as I please. that's why when I work on my first draft, I usually try not to scroll up and fix anything because then I will keep doing it and will spend more time on fixing past scenes rather than writing the current ones. if I want to fix something from a past scene or alter something I've already written (or add/remove things in), I make note of it under a list called "Second Draft," which I will use when working on the second draft in order to fix anything I had desired to do when writing the first draft.
