Some people think that spending time on hobbies and interests is a waste, but I completely disagree with them. In my opinion, following hobbies is meaningful and brings many benefits. First of all, hobbies help people relax and reduce stress after a busy day. For example, a student who loves playing the guitar may feel calm and happy when practicing music after school. This helps him forget the pressure from exams and improves his mental health. As a result, he can concentrate better the next day.
