Candidates can stay motivated during long preparation periods for UPSC by setting realistic and achievable milestones. Celebrating small victories, such as completing a chapter or scoring well in a mock test, fosters a positive mindset. Connecting with a study group can help maintain accountability and create a support network for sharing experiences. Regular breaks for self-care, exercise, or hobby activities can alleviate stress. Reminding oneself of the ultimate goal and envisioning success can reignite motivation and enhance commitment towards rigorous study schedules.
