Mrs. K. questions who she really is. Her family, her career, her entire life seem pointless. She feels anxious and broods. She sometimes screams at her children for no reason and then feels guilty. She has toyed with the idea of suicide. In contrast, Mr. M. believes that he possesses extraordinary gifts. He spends long nights writing down grandiose plans to save the world and sends his manuscripts to numerous publishers. Despite heaps of debt, he buys an expensive sports car, anticipating success.

Relationships, careers and happiness suffer when reality doesn’t match who we think we are.
