Now that I want to try writing fiction again, I thought starting with smaller projects would be a good start. I vaguely remember writing a few short stories (or one shots) growing up and encountered some major challenges along the way. Due to my inexperience with story telling, I was unable to work around these. I fear about running into these again, so here are a few questions for tips: 1. How many characters should there be in a one shot? 2. How can one write solid character development with so little space? 3. What do you consider the ideal length for a short story? (my old ones were around 20 pages, but they felt rushed) 4. Does the scale of the story need to smaller in order to accommodate the short length?
