As the saying goes, three points are doomed, and seven points depend on hard work. We have to deny that our efforts are indeed quite important, but we also have to admit that parents' inheritance plays a vital role. It is said that the heritability of IQ is 0.68, that of literature and history is 0.45, that of science is 0.34, and that of eloquence is as high as 0.68. Some studies have found that mothers play a more important role than fathers in intellectual inheritance.

And the education problem you mentioned. Education is particularly important in the case of congenital genetic imperfection. The degree of family harmony and the educational level of parents are very important factors. Personally, I think that the so-called good education is not how many "three good students" children have passed the exam and how high their test scores are, but how to let children grow up in a healthy environment and form good habits, cheerful personality and healthy psychology. What is more important than having these attributes in today's society?
