Naguib Mahfouz, in "Sugar Street," emphasizes the importance of action in life, suggesting that belief systems must be rooted in faith. He argues that simply having thoughts or dreams is not enough; one must take concrete steps toward achieving their goals. Faith serves as the driving force behind these actions, enabling individuals to persevere in the face of challenges.

The quote reflects the need for a robust belief system that encourages and sustains life. Mahfouz invites readers to consider how they can cultivate beliefs that empower them to act meaningfully. A worthy belief system not only motivates individuals but also aligns them with their purpose, pushing them to create a fulfilling existence through their actions.
