You can't arrange your son's life, just as he doesn't want to study, so you can't do anything about him.

You don't know your son well enough. Even if he talks freely, you always listen to others. Have you ever thought about how he arranges his life? You can't help him here alone. When you finished, you found that this was not what your son wanted at all.

Your son's education is lifelong education. No matter how busy you are every day, you should take time to talk to him. Besides, he is almost an adult now, so consider him an adult. First of all, you should know what your son wants most. What he wants to learn most. You can't let your son learn because the industry in this society is profitable and most needed.

As the saying goes, interest is the best teacher. If he likes something, he will be addicted to it. Just like he plays games, he sits for hours at a time.

Specific analysis of specific problems. I suggest that what you should do now is to ask your son honestly what he wants to do and what he wants to learn most. When you know what your son needs most, you can come up and ask what you want to do
