In part 3 of IELTS speaking, it really helps if you give personal examples:
1. Do you think it's important for people to have hobbies? Why?
Yes, I think people need to have hobbies because we all need to do things we enjoy in our spare time. In my case, I find that playing football once a week with some friends helps me to relax, keep fit and forget about work. I think it's the same for everyone.
2. Can hobbies have any negative effects?
Yes, if you spend too much time on your hobby, it can affect other parts of your life. I remember that one of my friends spent most of his time at university playing computer games instead of studying. In the end, he failed most of his exams.
