Aspirants face several challenges when studying for the UPSC while working. Time constraints make it difficult to cover the extensive syllabus systematically. Balancing professional responsibilities with preparation creates stress and limits study hours, leading to potential burnout. Additionally, the demands of work can affect concentration and retention of information. Working candidates may also lack access to critical resources like libraries or study groups, making self-study challenging. Overcoming these obstacles requires efficient time management and disciplined study habits to maintain a healthy balance.
