Be beyond doubt the foundations and inspirations of your character. A character without inspiration creates a destitute storyline, but more vital character inspirations are the key to creating the character throughout the storyline. What convinces your character? What are her needs and her needs? If the character is doing something deliberately, why is he doing it? An example of this would be Suzanne Collins' Starvation Recreations when Katniss volunteered for recreational activities so that her sister did not need her. She made it to her since he adored her sister to her.
