In Margaret Atwood's "The Handmaid's Tale," the protagonist emphasizes the necessity of managing one's thoughts in a challenging environment. She indicates that excessive contemplation can lead to distress, reflecting a reality where engaging in certain thoughts is not only burdensome but also potentially dangerous. The sentiment underlines a survival strategy in a repressive society where mental freedom is stifled.

This perspective illustrates the broader theme of control over the mind and body within the narrative. By rationing thoughts, individuals can navigate their oppressive circumstances with greater resilience. Atwood's exploration of mental constraints resonates with the struggles faced by characters who seek solace in selective thinking to cope with their harsh realities.
