In Jonathan Lethem's "The Fortress of Solitude," the quote "Develop your pawns or Hulk will smash" serves as a metaphor for the importance of nurturing one's potential and resources in the face of challenges. The reference to the Hulk, a powerful and uncontrollable force, emphasizes the consequences of neglecting development and strategy. This can relate to the necessity of careful planning in various aspects of life, whether personal or professional, to avoid being overwhelmed by larger problems.

The quote suggests a stark choice: invest time and effort into cultivating your abilities or risk facing the destructive outcomes of inaction. It highlights the theme of growth versus stagnation, reinforcing the idea that proactive efforts toward development lead to greater resilience and strength. In essence, Lethem’s narrative encourages readers to recognize the value of their "pawns"—the small elements in life that, when developed, can lead to significant successes and prevent downfall.
