Hey Linh!
 Long time no see, how is everything going? I'm doing great! You know, I love to watch TV a lot but only when I have free time. There are many interesting programs to watch on my TV like cartoons, science experiments, Vietnamese cuisine, and so on. I like English programs the most, in VTV 7 there are follow us and IELTS face off. Those are two programs that I like the most because it is very useful and it helps me to improve my listening and speaking skills among them I also like to watch science experiments and cooking shows. But it will be even better when I watch it on Youtube because there are a lot more things to watch and there are many themes that we can find to watch, for example: How to draw, how to learn English, how to speak like a native speaker and more...but you need to be careful when you watch youtube because sometimes there are programs that are not suitable for our age and it will affect our learning and our psychology. As I was saying, Youtube can have bad things and good things but the most important thing is how much we spend time on it, although we can learn through watching youtube it is harmful to our eyes so I think we should watch at least half an hour or two hours a day then we turn off the television, go outside and enjoy the fresh air.
 You see, I used to be addicted to the internet and every day I spent three or four hours on the computer and then gradually I formed the habit and rarely went outside to play with my friends. Because I used the computer too much, I didn't focus on my studies and I got bad grades when I went to school, when I got home I felt very disappointed in myself, from then on I was determined to change my bad habit and gradually I improved the habit. I now always go outside and play with my friends but I still use the computer( at least half an hour a day) to study online and I mostly watch English videos, thanks to that I got a high score on my exam.
