A lot of us study hard in school and get good grades in order to go to get into a good college. Some of us study hard only because our parents tell us to do so. Some of us are competitive and can't stand being ranked lower than someone else. A few study hard simply because of the sake of learning.
Whatever it is, why do you study hard? Is it all for college, peer pressure, parental pressure, self-motivation, etc., or is it more than that?
