We often say that hard work is the least useful thing. In fact, this statement is meant to break a bigger misconception: that hard work always pays off. For the wealthy, hard work more easily leads to rewards; for the poor, if this statement is taken as an absolute truth, it can become a shackle. Because the efforts of the wealthy are more likely to receive positive feedback in terms of resources, opportunities, and social circles; while the efforts of the poor still have to contend with variables such as background, rules, resources, and the era. Hard work is certainly important, but it is only a necessary condition for success, not the only one. Hard work determines speed, but positioning determines probability.
