This isn’t about being obedient. You will need these when you grow up, and if you don’t learn now, how are you supposed to live on your own? Do a nice thing to your parents, not for making them happy, but if you make others happy, you will feel a better person too.
You don’t have to always be obedient, but be respectful. Not only to your elders, to everyone, even the bad kids in your school. You will earn respect from others too and feel happier, because you know you are doing the right thing.
Pay attention in class and do your homework. Use a weekly planner, so you already know what you have to do! Study and work hard. Parents and teachers don’t only look at your grades, they look if you studied or not. If you get a bad mark, don’t worry. Just don’t hide it from your parents, they will find out anyway. They care about your education, not your grades. Consider that studying is a privilege. Lots of children, especially girls, don’t get access to education. Even if you don’t go to a private school, you are still luckier than many children in the world. And, education will lead to better jobs and to a quality life, and of course to culture. It makes you more creative, more intelligent, and teaches you to not believe everything, to give you your own opinion, to not follow the wrong paths, to not repeat the same errors in history! It makes you understand more, know more, and see the world as it is. So, study for yourself, not for your parents and marks!
Maybe your style needs makeup, in that case, if your parents allow it go for it! This isn’t for your parents, this is for you. Make-up is fun, it makes you experiment and feel different, but if it becomes a mask that you can’t leave, ask you some questions. And remember, everyone can be beautiful even without makeup!
