There is a dangerous thing that school teaches: it teaches obedience and to dedicate your life to said institution. This is a dangerous thing to teach, because not only does this make people feel oppressed, but it also makes people feel their life needs to be dictated in order to succeed, when in reality it should be the opposite. The only person that should dictate your life should be yourself. I’m not saying not to set your restrictions (self-restriction can be quite useful), but I believe that unnecessary restriction on your life is harmful and dangerous.
Do not let teachers completely mold your mind. I’m not saying all teachers are bad. Many teachers have useful ideas and many are great people. What I mean to say though is that to let authority figures control your thoughts and ideas completely is a dangerous thing. What’s important is that it’s your brain, your thoughts, your body, etc. You have a right to disagree with the ideas of an authority figure, you have the right to make your own opinion on something whether it agrees with the beliefs of said teacher or not. It’s what makes us individuals. Our own thoughts and ideas help create or improve upon older ideas, or create entirely new ones (sometimes based on old ones which we found some things wrong with).
It’s also important to find out your passions. What you want to do in your life, what makes you happy. I’ve seen people who are rich and at the top who are not satisfied with their life, because they feel that haven’t fulfilled anything that would make them proud. Instead of following what society wants for you, it’s better to try to find what you want for yourself, as long as it’s realistic enough to be achieved. We can’t all achieve everything methodically overnight. Some things take more time than others, and some people manage to get there faster than others. We all move at our own pace. We all have different personalities which makes us unique. We aren’t all this one personality that institutions like school demand us to be. We’re all unique (though there might be people in this world who are nearly exactly the same as you are). Let yourself dictate yourself, at least for the most part, not others.
