Anywhere between 2 hours and 2 days to write my first draft (usually about 3k words long).
Then if Im iffy about what I wanna write then I give it a pass through, ideally the next day.
Then I do one pass with Free Grammarly, in particular scanning the red and blue underlines. I dont have the pro, and I often find I like how I phrased a sentence better than how Grammarly would. That said I'm writing in first person so I get a lot of leeway with that. Third person I'd have to be more flowery.
Then copy it back into SH editor and do final revisions.
At the end of it all, a new chapter is born, whereupon it will be seen by 5 people and get 1 heart xP (I am extremely grateful for thosecwho continue reading my work, it lets me know I am positively affecting someone's life.)
I should start looking up random words in English to see if I can add anything new on the vocab front, but I find a more conversational style works too.
