tbh, even though a lot of people seem to hate it, I
love outlining. For my multi-chaptered stories, I make ridiculous chapter-by-chapter outlines with a detailed summary of all major events in the chapter, brief summaries of the minor parts, questions, footnotes, a quick paragraph about the "point" of the chapter and what I need to convey, etc etc etc. I swear sometimes I spend more time on the outlines than the chapters, but it does prevent me from writing any filler and keeps my story well-written and on track so it's worth it.
Also, I love that moment when I realize something I've written is actually really, really good, whether it's a certain paragraph, an entire chapter, just a line or two, etc. Just when I read over something and go, "
Damn, that was awesome." idk, maybe I'm just narcissistic but I love that feeling.
and creating characters, of course.
