If you want to tell a great story, conflict is key. Creating conflict doesn’t necessarily require a fight, like when Batman battles the villainous Jokers or Penguins of Gotham City. You simply need to set up some form of tension that the hero must overcome.
Maybe conflict arises as a hero struggles to accomplish a difficult task. Perhaps it’s from the hero’s attempt to overcome unfair circumstances. It could stem from a hero’s battle against him or herself, like confronting internal doubts they can succeed or accounting for previous poor decisions. Or maybe a T. Rex is chasing them all around Jurassic Park, creating reason to doubt they’ll make it off the island alive.
Whichever type of conflict you choose to create, establish clear stakes so that your reader will be more likely to care about the hero’s success – and remember their story well after they finish reading.
