My son said that he had no goal in his study, so he had no motivation to study. As long as he is willing to work hard, his academic performance will certainly improve. Tell me how to write to my son.

First of all, I understand your urgency as a parent, but I have neglected many factors. For example, children's learning status, learning environment, their own foundation, primary school, middle school and high school are not clear. I can't find the point if I want to say it. If you see that you can @ me, I am happy and willing to answer for you.
