Status Updates From The Devil Wears Prada

In the book "The Devil Wears Prada", Andy Sachs has started her job as an assistant at Runway. Miranda, her boss, gives her impossible demands that test Andy's patience and willingness for her dream job. Miranda always ends her demands with a comment like: "A million girls would kills for this job" (Weisberger 12). I am confused why Andy hasn't quit yet, but I predict Andy will change who she is to hold onto her job.
