Distance is painful, specifically, the distance between expectation and reality. If the distance is too long, people will suffer.

When a person is young, he loves a girl until tea and rice are not fragrant. Perhaps it was because a smile lit the fireworks in his heart. But this kind of flame has formed a prairie fire, and his desire is expanding day by day, but he can't release and satisfy it. That desire makes a teenager feel physical and mental pain. Some people become poets in pain, while others become crazy in pain.

Middle-aged people will feel pain because of their ideals, and the beautiful picture in their hearts will still stay in the distance. Even if he made a reasonable plan according to his present occupation, he is still far from that dream. Such a distance made him feel pain. I am also in this ranks. In the embarrassing period of life, when people reach middle age, they soak Lycium barbarum in a thermos cup, and their health is getting worse every day, but the burden on their shoulders is getting heavier and heavier.

Parents need to take care of their children's education funds and plan ahead in their later years. All the factors will come down to one point, that is, time is tight and the task is heavy.

For an old man, he will face both physical and psychological pain, because the door of heaven is like a lamp, which will open to him at any time, and he will have to accept the reality of death. On the other hand, his health is getting worse every day, that is, keeping in good health is the most important thing now, but after all, time and tide wait for no man, and that day will come, so some people pack up these pains and give them to religion to get rid of.

To put it bluntly, the root of the pain is that the life we are living now is not what we want, and the gap between ideal and reality is painful.
