Returning to an earlier post, let's talk about another change which can occur in your stories. One of the most popular methods for writers to utilize is the "character change." In this type of story, the characters grow and change from the beginning to the end of the story. This can be a change for the good, although sometimes it's a change for the bad.
There is a process you should follow for your character change story. First you need to make your reader believe that your character has the ability to change. You can do it one of two ways, either by showing he has the qualities to change now or had those qualities in the past.
Once the reader is convinced, you have to add a reason for the character to change. Force your character into a situation where he or she must change using conflict of some type as a major impetus. Generally speaking, most people won't make changes in their lives unless there is a compelling reason to do so. Make sure that reason is there for your reader.
Don't drag out that moment your character realizes he must change. Move your story forward and allow your reader to decide what has happened by your character's deeds.
Once your character has changed add validity to those changes by showing a concrete action performed by your character.
If you incorporate all of these pieces into your character's growth during the story, you will have created a compelling piece your reader will enjoy.
