There are always many conceptual differences between parents and children of every generation, not just our generation. Because of the different growth environment and education level, it is normal that parents' ideas are different from ours. When this difference occurs, it is meaningless to communicate with parents forcibly.
Tell your parents what you think and expect their understanding and support. There are differences in ideas, but the problem is not big. Parents' ideas are also for your better life. If you have your own life plan, of course you can. You can make this plan clear to your parents and let them know that you have a comprehensive plan for the future instead of wasting your life at will.
First of all, you must try to communicate with your parents, so that you can know what kind of attitude your parents have, and then you can decide what to do next.
If communication is not smooth, then you should listen to your parents honestly and there is no need to refute them. After you go out, do whatever you want. I think this is the best way to reduce the conflict between two generations, because you can't change your mind, obey your parents, and you can't persuade your parents to support you. Then when your parents preach, you'd better try to keep silent. If you have a big heart, you can say yes.
After all, I have to go out and do my own thing. When you do it, just follow your thoughts, but no matter what the result is, you must learn to bear it yourself. Otherwise, it is a bit nonsense to attribute success to yourself and failure to parents.
When communicating with parents, we should minimize confrontation, otherwise the contradiction will become more and more acute. State your thoughts and do what you think. Whether the communication with your parents is fruitful will not affect your belief in doing things, but will give you a reason to prove yourself. Let parents talk about it, and you may be unhappy if you hold it in your heart; Work hard. When you succeed, they can understand without communication.
