UPSC aspirants develop a sense of public service through various means like participating in community service, engaging in social issues, and understanding the role of civil servants in nation-building. Involvement in NGOs and attending workshops on governance can further enhance their awareness. By reading biographies and case studies of successful civil servants, aspirants can draw inspiration and develop a commitment to social responsibility. Discussions with mentors and serving officers also help candidates connect personal motivations to the broader goal of public service in India.
