You don’t have to write one story at a time, even in the same story. You can write a story that cuts from one story line to another with thematic or narrative connections. Usually each story line progresses chronologically, but they may be taking place in different locations, in different time periods, or to different people. If you need a story idea, here are a few:
• This is a story about people trying to prevent a war whose causes have deep roots.
• This is a story about a disaster that depopulates Earth, and about a village that is founded later on to repopulate it.
• This is a children’s story about three young people who each meet the same talking dog.
