What ultimately drives Vincent to pursue his goal in GATTACA?

Vincent’s journey in GATTACA is primarily motivated by his ambition to prove his worth beyond genetics. In a society that heavily emphasizes genetic predisposition and engineering, Vincent, who was conceived naturally and labeled as "invalid," strives to demonstrate that one’s abilities are not solely determined by their DNA. His character embodies the struggle against societal prejudices and limitations imposed by genetics. Vincent's defiance of these constraints propels him to chase his dreams of space travel, illustrating a deeper desire to establish his identity and value through personal effort and determination rather than relying on the advantages that genetically modified individuals have. This pursuit emphasizes a central theme in the film: the triumph of human spirit over deterministic views of biology.
