The topic is an evergreen among writers, especially of fiction:

  • do we more or less construct our entire story up front, before beginning composition, including characters, backstory, plot arc, etc. Or perhaps
  • at least an outline of the main features of the plot and main characters, or
  • have a vague idea of who and what it’s about and sort of wander into it and see where it goes, or
  • name the protagonist and let him or her take it from there?
