Maybe you have seen many people around you who don't like their jobs very much but can't change anything. They studied really hard as students until they chose their majors without putting much thought into. Most of them never thought carefully about the relationship between their future career and the majors chose. Many of them found that they didn't like their majors after entering university, even if they achieved top scores during the National College Entrance Examination. I heard about an excellent student who got a very high score to get to the best university in my country, but he didn't like his major. He just wanted to be a doctor, so he decided to study medicine after graduating from his university. Meanwhile, some of his peers have learned medicine for four years. It sounds really terrible! So, planning your career is the most important thing in your life. If you turn your hobby into a career, I think that you will definitely like your job. If you like your job, you will definitely try your best to do it better without feeling tired. If you do your job well, you will definitely prove yourself. We always hear that (OR "People say that...) hobbies are the best teachers!
