Setting realistic goals is vital in UPSC preparation as it provides clear direction and maintains motivation. Achievable milestones create a sense of accomplishment, reducing stress and anxiety. Unrealistic expectations can lead to disappointment, discouraging candidates from persisting in their efforts. By breaking down the syllabus into manageable sections and defining specific targets for each study session, candidates can track progress more effectively. Furthermore, realistic goals allow learners to recognize their strengths and weaknesses, fostering a more focused approach to improvement and adherence to an effective study schedule.
