We often say that hard work is the most useless thing. In fact, this statement is only meant to break a bigger misconception: that hard work always leads to rewards. For the wealthy, hard work more easily yields returns; for the poor, if this statement is taken as absolute truth, it can become a shackle. This is because the efforts of the wealthy are more likely to receive positive feedback in terms of resources, opportunities, and social circles. Meanwhile, the efforts of the poor must also 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 position determines probability.
