As a writer, I know it's difficult to get inside your characters' heads, especially if a character is different from you. Creating believable characters means getting to know a character all the way down to the core of his or her being. If you're finding it hard to identify with your character and figure out everything that makes him or her tick, consider trying the following strategies:
Write an entry in your character's journal.
Write a letter from your character to a friend or loved one.
Walk, talk, eat, and move like your character for a set amount of time.
Write a bulleted list of important moments in your character's life.
Make a playlist of songs that remind you of your character.
These are just a couple of techniques for getting over writer's block where characters are concerned.
