That’s not entirely what I meant. Of course characters are important. But is it necessarily important for them to have a goal or obstacle? Or can they be along for the ride like the reader?
Characters drive your story. Readers want to be involved with your characters, not so much the story. Imagine a TV documentary. The plot is stale and the characters are non-existent. You watch the documentary because you’re interested in the subject (plot) yet you could never say the documentary is an exciting story. With characters, you inject so much more into your story. You could have a large array of characters that come and go, but it is really hard to pull off well.
