What are the motifs in The Truth About Forever by Sarah Dessen?

Perfection is a recurring idea throughout the novel as Macy strives to be perfect for a number of reasons. When the story begins, she is anxious to prove to everyone around her that she is OK following her father's death, so she works hard on her appearance, her grades and her behavior, believing that nothing short of perfection is acceptable. She frequently mentions that Jason is perfect, not realizing that he is simply disciplined to the point of being robotic.
