Characters are a product of their life’s experiences. The things they seen and done are major influencers in who they are at the time of the story. From birth, the people in their lives affect what they believe, what foods they eat, the clothing they wear, the attitude to education that they have.
Imagine a character who grows up in a loving, fostering home. His attitude toward obstacles life presents will be completely different from obstacles that pop up in the life of someone who was abused in some way. It makes sense. In the first situation the character might love challenges and new experiences while the second individual might be fearful and prefer hiding at home.
When you create a character you need to construct their life’s journey as a background into who they have become. This is different from a character arc. The arc traces the character’s trajectory throughout the story, encapsulating the events that change her as the story progresses.
The life’s journey shows the path that she walked as the years passed by.
Your task is to create a life’s journey for a new character that you would like to include in a story. Graph paper might be the best source as it allows for increments of time spaced out in measured blocks. Start at a point when they first event occurred. This could be birth or the first day of school. Add elements that played important parts, both negative and positive.
When finished, using the data you’ve detailed, write a memoir-like story of his life.
Have fun with this one.
