Instead of being convinced, Vincent was empowered and inspired by the following:
* His own determination and resilience: Despite being deemed "invalid" by the society he lived in, Vincent never gave up on his dream of traveling to space. He was willing to go to extreme lengths to achieve his goal, even resorting to illegal means to get what he wanted.
* The support of his family and friends: Vincent had a supportive family, particularly his brother Anton, who encouraged him to pursue his dreams. He also found a friend in Irene, who saw past his genetic "flaws" and recognized his true worth.
* The belief in the power of will over genes: Vincent was a firm believer that his potential was not determined by his genes, but by his will and determination. He saw the flaws in the society that valued genetics above all else, and he challenged the status quo with his own actions.
Therefore, Vincent's conviction wasn't a result of being persuaded by others, but rather a manifestation of his unwavering belief in himself, his dream, and his potential. He wasn't convinced; he was determined.
