I think part-time work is a way to practice one's own skills as well as a way to initially become financially independent in teenagers. Of course these jobs have many benefits in terms of developing skills and improving income but nothing is completely harmless when overdone, of course part-time work is no exception. . If you know how to balance time for work and time for living activities, it will not affect you at all. But if your desire to work part-time takes over your day, I think that's a bad way. Working too much will make you tired, lethargic, lacking vitality and energy, making you suffer from many diseases and affecting your schoolwork. Working to overwhelm your study time will prevent you from completing your homework and having time to review old lessons, which will affect your study results. So you should balance part-time work and lifestyle activities to have good health and be able to actively absorb the values that part-time work brings.
