Compared with watching others gloat in the pit and get happiness, the happiness of educating people is stronger and more lasting. Being a good teacher is a habit, from which you can really get happiness. The secretion of dopamine is recognized and respected by others. If this habit is too strong to talk about objects and occasions, it can only be said that the habits of the older generation are not good. If the older generation thinks another young man is hopelessly stupid, he will never educate this other young man. Believe me, the older generation will only laugh and be noncommittal, and will not waste their limited lives and words. Finally, if the older generation really cares about that other young man, and according to their own experience, it is speculated that this young man has a pit in front of him and is not afraid of being rejected and goes to education, its starting point is still worthy of respect. This shows that the young man is taken care of. Distinguishing the above different situations requires intelligence, emotional intelligence and understanding of others. Most people, including me, didn't have it when they were children. It's not a pity, the world is like this. Fools are always stupid unless they turn over; People who expect you to be a fool will not educate you; Fools themselves feel that they don't need education. This is what human nature itself looks like.
