In a longer running story, how do authors continue to demonstrate a character's constant growth without reaching a plateau midway through the story? Especially for a main character in a story, where the character is constantly under the reader's attention and always undergoing situations and meeting people that change the way s/he thinks, how do you continue to make your protagonist evolve as a person without hitting a point where it's like, "well, she's resolved most of her original fears and insecurities, and she's become a pretty decent person. now what?" Maybe I'm looking at this wrong, but I feel like after a certain point, continuing to see the character make bad choices or fall back on old fears or habits might feel stale and repetitive. As a reader, I know I sometimes feel disappointed when a character in a story just doesn't seem to learn from his/her mistakes. But at the same time, if they shift their attitude too quickly, it feels rushed and unrealistic... so I think it's difficult. What elements do you introduce to your story, or what techniques do you use to continue to make a character evolve and progress in a believable way? I'm a very beginner writer just starting to try this as a hobby, so I would really welcome any tips and pointers you might have.
