What does your character like to do for fun? It’s an important criteria to consider when creating a given character, for such activities influence the events of the story.
For example, if your character began swimming competitively as a child and still swims today, then when he has free time, he’ll choose to go to the pool. It also means that he could use his skills to solve a crime or create a crime.
Scrapbooking is a huge business right now. Many people love to organize photos and memories into these books, pasting in not just pictures, but also decorations that support a given theme. If one of your characters likes to scrapbook, then the finished products could be used to search for a missing child, decorate a hall for a banquet, or evidence to convict a criminal.
Your task is to create a list of activities that your character might enjoy. It might be important to stick to those things that you are familiar with, unless, of course, you want to spend time researching. Try to get at least ten items on your list.
Then willow it down to the top five. Embellish these five by listing when and where and with whom the activities take place. For example, swimming could be a solitary activity, or it could be team-based if your character continues to compete today.
From this expanded list settle on one that feels most like your character.
Now write a scene in which she prepares to participate in this activity, or tells someone about it, or tries to convince someone else to join in. Don’t flood the reader with details about the activity, but rather let the reader experience it through the eyes of the character.
Have fun with this one.
