Be careful of the logic here though. He is a genius (or has special talent on something) not because he studied late. Since he is particularly good, he does not need to study early and can still beat others. I do not think "studying late" makes him a genius, but rather, again, since he is a genius, so he can afford to study late.
If one has a genius child, you do not need to push. For ones who are not genius, I do not know.
