Parents expectation from child

Like all parents I want my son to be disciplined, don’t eat junk, eat healthy, sleep on time, take interest in his studies, have good manners, listen to elders, be nice to everyone, become something in life … and the list goes on. But often I think should I burden my son with my expectations? Am I putting too much pressure on him by asking him to study well, study daily, be disciplined? Am I stealing away the fun of doing something when I say whatever you do, do well? Did I do right by scolding him? Did I do right by hitting him?
