I’m glad to hear that you like my stories :). It’s pretty normal to be nervous about posting a story. I was when I posted my first few books. When it comes to writing them, I’ve listened to music while typing to help keep my mind going. I try to use a variety of words so that it doesn’t get too repetitive. When I’m not working on a chapter, I reimagine the story in my head and picture future events for the rest of the book.
I hope this helps. Let me know if you need anymore tips. I’d love to read it :).
