The third point is to find his favorite activities or hobbies, help him make the highest level, and give him a great sense of accomplishment and happiness. Then he will be particularly willing to listen to me, and then he can drive his study. My son took him to play table tennis in primary school, and as a result, he was the second in the school. Every time he came home, he shared his happiness with me and asked if many people came to watch him play. Then I talked about the importance of learning, and he was willing to accept suggestions. Later, junior high school and senior high school all liked playing football. I even helped him cope with the strict teacher and let him play football in a hurry. I can imagine how grateful he is to me! So he has been studying and doing things with special care. The above is my answer, hoping to provide some help to friends in need.
