To have a story, characters have to be placed into situations where they have to make choices, and those choices have to have consequences for both the character and the story. In other words: things have to happen.
"Everyone is in some way trying to be the same. Stay off of that. Develop yourself so you have your own voice. So that it's you they are looking for, not X. Develop a style, a way of working." — Mark Ruffalo
