The quote emphasizes the importance of focusing on the positive aspects of life rather than getting distracted by what is lacking or imperfect. It suggests that while everyone has goals, maintaining a perspective that highlights the opportunities and rewards (the "doughnut") can lead to greater fulfillment. Meanwhile, fixating on difficulties or shortcomings (the "hole") may detract from one’s journey and achievements.

In Margaret Atwood's "The Blind Assassin," this insight resonates with the broader themes of the narrative. It invites readers to reflect on their aspirations and encourages them to appreciate their successes and joys, instead of being bogged down by obstacles. Ultimately, the message serves as a reminder to cultivate a mindset that celebrates possibilities rather than deficiencies.
