I find this argument to be very interesting. It may be true that "he" studies more than the average person... but doesn't that mean that "he" IS smart?
"He" is smart enough to study harder than everyone else. "He" is study smart because "he" is smart.
This is like saying "he is only better at baseball because he plays all the time." Or "I would be as strong as him if I worked out as much as him."
It doesn't make you any more successful by belittling the accomplishments of others.
