How to understand the saying that human beings are as thin as paper, and the meaning of human beings?

I, not a big money, nor a big official, I, no power, no money. I am just an ordinary and simple person, as ordinary as grass, as clear as water. Through many ups and downs, experienced the twists and turns of life, I understand, human thin as paper, the heart is muddy, some road must go, some suffering must be their own, look to others, is not a long-term plan, rely on others, no one will respond to you. Ask people, but also see others face; Use people, but also listen to others verbose. Don't cling to the past refused to go, don't rely on once don't let go. When a person ignores you, don't be sad, everyone has their own life, who can not always accompany you. The most embarrassing is to overestimate their position in the heart of others, in fact, you know clearly, the most humble but feelings, the most cool but the heart. You must understand, to go people can not stay, pretend to be confused not to wake up, don't like you moved. Others help you, that is love, others do not help you, that is duty, rely on anyone is a kind of wishful thinking, their own happiness and dream in their own hands, belong to their own wonderful life, only by themselves to create. Their own pain to eat, their own pain to suffer. Don't put your hopes in others. No one wants to overfeed the same people. Don't make excuses, but complain more. Put the heart, a good state of mind, cry over the pain, long memory, continue to move forward until the end of life. Forward it! The structure of herringbone is to support each other. Therefore, it is necessary to improve their utilization value. Only in this way can we support others and ourselves. Otherwise, who else would you support but your own mother and father? On the other hand, it's good to be used. Wolves walk thousands of miles to eat meat, sheep walk thousands of miles to eat grass, people's heart, only the interests of the most Lord. There are also kind people, not many. Be self-reliant. It's up to you to thrive. Cold years, everyone is not easy to live, for the rich people, and others common rich, nothing for no money, is not each other, cold eyes relative. Very painful but do not shout, very tired but do not say, and not feel, nor do not feel, pain, no one understand, shout out and what, tired, no one help, say it again; Have bitter but do not say, tears but do not flow, not do not want to say, also do not want to flow, life, a lot of bitter time, the tears quietly swallow, life, cry a lot of time, gently hide the bitter. Life is bitter and happy, bitter, I can do, tears, I do not flow. People's life is not easy, cry tired pain, fall and climb up the foot of the road, or step by step to go down, the scenery in front of the more beautiful, all their own fuel, stride forward. Life is like this, parents, friends, husband and wife, comrade help, social help, the end is limited, often ask people, as oneself, ask people as oneself, can not rely on the day, can not rely on the ground, finally rely on their own.
