In Jonathan Safran Foer's book "Everything Is Illuminated," the narrative reflects on the concept of time and distance. The phrase "Tomorrow was over the horizon" suggests that the future feels distant and unattainable, emphasizing the uncertainty that accompanies the passage of time. It evokes a sense of longing for what lies ahead, illustrating how the anticipation of tomorrow can sometimes feel overwhelming.

This idea continues as it stresses that reaching tomorrow would require an entire day. It captures the essence of life's journey, where each day brings challenges and the inevitability of facing the future. The metaphor serves as a reminder of the obstacles that often stand in the way of progress, highlighting the importance of patience and perseverance in navigating life's uncertainties.
