Who suggests that one should try repeatedly if initial attempts fail?

In the context of "GATTACA," Jerome suggests the idea that perseverance is key, particularly when initial attempts do not succeed. This aligns with his character's journey, which encompasses themes of determination and resilience despite facing numerous obstacles. Jerome's experiences reflect how individuals must push through challenges, reinforcing the notion that failure is not final and that repeated efforts are often necessary for success.

The other characters, while influential in their own ways, do not explicitly emphasize the importance of trying again after failure as strongly as Jerome does throughout the narrative. Thus, his character embodies the message of persistence in the face of adversity, making this response particularly fitting.
