Public service motivation influences candidates' performance in UPSC by instilling a sense of responsibility and commitment towards societal welfare. Aspirants driven by a desire to serve the public are more likely to engage deeply with their studies, fostering a genuine understanding of governance issues. This motivation can enhance persistence, focus, and ethical behavior in their preparation. As they encounter challenges, their intrinsic desire to contribute can inspire resilience and innovation in problem-solving. Ultimately, candidates who embody public service motivation are better equipped to succeed in both the exams and civil service roles.
