Now, I'm going to give a talk about hobbies.
To begin with, a hobby is an activity that people do for pleasure in their free time. As far as I know, the most popular hobbies among teenagers are listening to music, playing video games, watching films, and taking photos. Some teenagers also enjoy drawing, reading, dancing, or playing musical instruments. In my opinion, having a hobby is very important because it makes life more interesting and helps us relax.
Speaking about myself, my hobby is playing the guitar. I started learning it two years ago, and now I can play several songs. I enjoy playing both classical and modern music. When I play the guitar, I feel calm and happy, and it helps me forget about my problems. Sometimes I also write my own short melodies, which is really exciting.
As for how much time I spend on my hobby, I try to practise every day for about half an hour. At weekends, I usually spend more time playing the guitar, sometimes up to an hour or more. I also like to learn new chords and songs from the Internet.
Regarding my attitude to having a hobby, I believe it is very beneficial. A hobby not only helps us develop new skills but also gives us a sense of achievement. It is a great way to express ourselves and meet people with similar interests.
In conclusion, I think everyone should have a hobby because it adds colour to our lives and makes us happier.
That's all I wanted to say about hobbies.
