What are the motifs in Replay by Ken Grimwood?

Control is a recurring idea in the story. Jeff struggles to try to control his life and his destination. When Jeff realizes that he is replaying his life, he tries to change the course of events and control what happens to him. However, Jeff is never fully successful. He can never truly control what happens. Jeff is able to make money because of his knowledge of the future, but he cannot control his relationship with Linda. He cannot control his own death in 1988 or change the fact that whatever he does, he will lose what he has gained in the future.
