I'm horrible at answering these questions, and probably won't be of much help, but it depends on what you're interested in. I Cinta to write Paranormal Romance. But it's all about what suites anda and draws your interest the most. I hope this helped. lol.
when find it hard think of a story I just use my dreams if I have a really weird dream atau nightmare I try to remember as much as I can and put that into a story and add things it works for me
