I use a Git workflow to track my writing, which definitely isn't for everyone, but I really appreciate the assurance it gives me. But that's probably because I already use Git for work. Actually, I do write in a screenplay-like format sometimes. I call it "sketching" but there's probably a more formal name for it. Dialogue and action beats, and nothing else. It works well when I'm able to hear the characters in my head and I need to get their words down before I forget. Though there is a bit of a risk when you expand this into full scene, that your scenes tend to be very dialogue heavy. That's something I'm still working on. More specific advice is a bit hard to give without knowing where you are. Are you stuck on getting any words out on the page at all? Or are you writing the opening to your story over and over because it never feels right? Or something else? My experience was the first time I sat down to really write something, it felt horrible. I think I got about 50 words on the page after about an hour. It really was pretty discouraging, and of course the writing was bad too. I'm honestly not sure how I got through this phase. I think I just slogged through it because I cared enough about the story to keep going even though it sucked. One thing that may have helped is that I keep a journal. The rule for my journal is "never write anything boring". I am very inconsistent about it, but it gave me a space, before I really had the fiction writing thing down, to at least practice getting words on the page. I've been putting down about 100 pages a year for the last 10-ish years, and I realized belatedly that in a way this was my writing practice. I may not have written 10 fiction books, but I wrote their equivalent (at least by word count) in my journal. Reading helps too. I had stopped for a long time, and picking it back up has helped me really figure out what I want to be writing (usually because I have knee-jerk reactions to what I read, and that tells me something about how it's affecting me). There's quote I encountered recently that really aligns with my philosophy of writing: "the first draft is telling yourself the story, latter drafts are telling the story you want readers to read" (Farah Heron, but she might have gotten it from somewhere else). What this means is that it's ok for the first draft to not be something anyone else is going to want to read. The most important thing is that you like what you're writing. For me, writing has become a better-than-reading experience. I read a fair amount of books these days, but because my tastes are particular, it's rare for me to find anyone who is writing exactly what I want.... but I can write it myself.
