First of all, it can be said that your child is very self-motivated, but his personality is also very stubborn. Of course, he can also be said to have perseverance. To tell you the truth, I really admire your children. It's really amazing that he can have this kind of self-control. Therefore, you should let your child see his own advantages, you can see his progress in the innovation exam in the past two years, and you can also let him consider which one he is more suitable for. In fact, changing his choice does not mean that he has been smoothed by reality. Knowing how to change is often more important. If he is suitable for believing in the Olympics, then he will get good grades in this respect and be envied by others. It is also possible to take him on a trip, chat with him, try to enlighten him and tell him that he is great and his parents will always accompany him. If it really can't be solved, it is related to depression, so you need to consult a psychologist and seek personal advice. I hope it helps you?
