“My favorite hobby is playing video games. I have been playing video games for about 10 years because I find it stress relieving and let’s me take a break from reality. Sometimes I play videos games with my friends online or I play them by myself in my room. This hobby makes me feel competitive and rewarded for doing well.”
That’s my example answer, you should answer this question using your own hobby and your own reasonings. I just used my hobby as an example.
