Why don't some students study hard when their families are not very good?

You have never been poor. You don't understand. You tell a man who is dying of thirst that if he works hard 100 km, there will be an oasis, and he can't sustain it by his endurance. He just wants to have a well now. He is willing to stay in the desert for a month if the well is enough to drink for a month. For a poor man, the pleasure of eating a chicken leg and a pizza at noon is enough to satisfy him for several days. You call his situation complacency and lack of progress. Think about it, your so-called struggle is probably to work hard, earn millions of dollars a year, find a good wife, pay off the loan of the second ring house in Beijing within five years, and have two fixed travel times a year. I estimate that Wang Sicong would call your situation "complacent and not motivated". You have never been rich, and you don't understand. I once said a cliche in an answer that when we consider many things, we only speculate on the unknown from our limited experience. Many times, our experience may not be applicable. For example, the mainstream view in Zhihu is fitness English learning, but you really put it into your life. Can this be considered mainstream? This is the truth when you have money and no money. For us, if we don't study, we can't make progress. For the poor, learning is not progress. We should enter the society early to earn some money, so as to have a little chance of getting a wife. Don't they understand what you said about study and struggle? But their resource constraints can't wait for that oasis. They are willing to stay in this desert all their lives and hold on to this well that may dry up. You will retort, what if the well is dry? Life is ruined if you don't struggle out of the desert. But think about it carefully, do our struggles and pursuits come out of thin air? No, because we have a kettle in our bag. We know that this water is enough, and we may encounter the risk of sandstorm and getting lost at most, but it is still enough on the whole. However, for a person who is dying of thirst, many times he really can't wait that much. As said in The Great Gatsby, not all people in this world have what you have. And the last sentence of this sentence is: whenever you want to criticize someone, you must remember that not all people in this world have what you have. If we want to go deeper, the only thing that can be called universal humanity is that everyone wants to satisfy his pleasure constantly. For your level, your pleasure seems to be more "smart" than those from poor families, but in fact there is no difference between intelligence and ignorance, only the situation.
