At its most simple, conflict is fully understanding the characters within your story. What is the deepest desire of your protagonist, antagonist, and supporting characters? Then you need an opposing force that motivates those characters to move outside their comfort zone.

Think of the stories you love the most. Do you enjoy them because there is a perfect structure and by-the-books dialogue? Or is it because you see yourself (or at least a portion of yourself) in the story? Chances are it was the latter. Why is that? Well, as humans we long for connection and community, which generally results in us surrounding ourselves with like-minded individuals.
