Stress occurs when the pressures of life exceed one's ability to cope. Common signs of stress include feeling stressed, having difficulty concentrating, procrastinating on important tasks, and suffering from frequent illnesses. Stress can be caused by factors like schoolwork, relationships, activities, and parental pressure for students. Managing stress involves exercising, keeping a routine, focusing on self-care, finding hobbies, talking to others, and using music. While too much stress is harmful, some stress can improve focus, competence, and time management.
