A writing friend recently directed me to the website below about scenes and sequels that are intended to develop characters. Basically, it involves the protagonist’s reaction to a scene or an event in a story, and the process of emotions she or he goes through. Usually, I think this will come natural to an author, whether she knows it or not. I mean, how can a story exist if the main character doesn’t have a goal, and struggles? It can, but then the readers won’t have any reason to cheer for the character. Realizing how the character processes her emotions will help the writer further develop the character throughout the novel, because everything will reflect back to that scene (goal, reaction and eventually disaster). It is what drives the main character, which is what drives the plot, in my opinion. See the link below for more information about this technique.
