1. No matter how difficult it is, don't owe without repaying

In life, everyone experiences financial difficulties at some point. When we are in such difficult times, if someone is willing to lend us money, that person is truly good and sincerely wants to help us. The reason they can lend a helping hand is because they trust our integrity and dignity. Therefore, when we are in difficult situations and someone helps us, we must be grateful and remember it. When it's time to repay, we must not find reasons not to repay. Because a person's integrity is built by themselves. Whether others trust and rely on us depends on our own behavior.
2. No matter how desperate, never scheme against friends

The word "Bằng" in the word "bằng hữu" (friends) is composed of two characters "Nguyệt" ("朋": bằng, "月": nguyệt), meaning that a person without friends is like a life without the sun. Because a person's energy is weak and incomplete, everything needs friends' help and support in order to achieve success. Friends care for and support each other, like an umbrella that provides shelter in both rain and sunshine, accompanying each other in difficult times. If a person betrays gratitude and loyalty, lacks dignity, schemes against friends for personal gain, or betrays friends, it is destroying their own path and ultimately turning themselves into losers.
3. No matter how disappointed, never blame parents and relatives

Usually, outsiders only care about whether we are wealthy and prominent in life. Only family members care about whether we are tired in this life. Everyone encounters unpleasant things in work and life at some point. When a person suffers emotionally, they usually blame their family for not giving them enough love. Even when living with others and not getting along, they blame their family for creating such a living habit. Many people feel that their fate is unfair, and they harbor resentment and blame their parents and relatives for not giving them more. It's as if every unpleasant thing that happens is the fault of their parents and relatives. This society may seem unfair, but everything has its consequences, blessings, and the will of heaven. Therefore, holding onto resentment is not as good as being optimistic and finding a new path, so that whatever is deserved will be obtained, creating happiness and a good foundation for the future.
4. No matter how difficult, never lose your spirit

The spirit is like a person's bones. If the bones are lost, there will be no shape left. A person without strong, firm determination, and patience cannot establish a career. A person who is not afraid of poverty and hardship, works with a peaceful mind, corrects mistakes immediately, is the one who gains respect from others and is not looked down upon. On the other hand, a person who loses spirit at the first sign of difficulty, abandons their dignity, and gives up the chosen path cannot achieve their career, nor can they gain the respect and trust of others.
5. No matter how successful, never be arrogant

The ancient saying goes: "When the sky is crazy, there will be storms; when people are crazy, there will be disasters." Life is a long road with ups and downs, so when you achieve success, don't be arrogant, because arrogance is temporary and cannot last a lifetime. There is a saying: "People have people, heaven has heaven," meaning that there will always be people better than us in this world, so there is no need to look down on others. In life, many people fail miserably because they are arrogant and conceited. No one has good fortune every day, and no flower blooms forever. Those whom we once considered ordinary may later achieve greater success than us. Therefore, no matter how rich or successful we become, we should maintain humility. If a person can maintain the "boundaries" of being a good person and not lose their self-respect, they will definitely become a person of integrity in society.
People liken life to a play. In this play, everyone can choose their own role. Sometimes, by looking at the wisdom and insights of others' lives, we can empathize with them, and at the very least, change our own perspective on life. There are 7 principles of human life that the more we understand, the more beneficial it is:
Not knowing tolerance, even with many friends, they will all leave: The ancient saying goes: "When the water is too clear, there are no fish; when people are too critical, there are no companions." Being overly strict, always picking at others' faults, and unable to overlook the mistakes of others will lead to loneliness. Those who are overly calculating with the faults or wrongdoings of others cannot be tolerant, and cannot keep loved ones by their side. Therefore, for issues that can be overlooked, one should not be harsh, to avoid losing friends and loved ones.
Not knowing gratitude, even with outstanding abilities, it is difficult to achieve: Drinking water without forgetting the person who dug the well, those who plant trees today, those who enjoy the shade tomorrow. Fish are grateful for water, birds are grateful for the wind, gratitude is the foundation for a person to succeed. If a person does not feel appreciation, does not thank others for what they have done, and considers everything that others do for them as natural, as a matter of course, or as the duty of others, then that person is very indifferent, and to put it harshly, selfish, living without love or meaning. Such a person will find it difficult to continue receiving help from others, and although their achievements may be temporary, they will find it difficult to sustain them in the long run, and will find it even more difficult to achieve greater success.
Not knowing action, even with intelligence, it is difficult to achieve dreams: Knowledge or experience gained from books or others is like guidance, but action is what turns dreams into reality. To fully understand things, phenomena, one must personally take action and experience. Reading books is certainly valuable and necessary, but remember that life provides us with more valuable and precious lessons and experiences than those recorded by others in books. A person who has a dream but does not take action will never achieve what they desire, no matter how intelligent they are.
Not knowing cooperation, even with effort, it is difficult to achieve great things: Throughout history, when undertaking great tasks, it has been difficult to succeed alone, because great tasks are the work of many people. The wise understand that to achieve success, one must know how to cooperate, use people, rely on the intelligence, advantages, and strength of a community. Those who do not listen to the opinions of others, always insist on their own opinions, will often end up becoming lonely and failing, and will find it difficult to achieve great accomplishments.
Not knowing frugality, even with good money-making skills, it is difficult to become wealthy: In today's modern society, many families, even if the husband or wife has a very good career and is very good at making money, may still have a troubled home, lack of harmony, and even separation because the other half or children are excessively wasteful and do not know how to be frugal. There are also many cases of winning a large sum of money, suddenly having a large amount of money that could not be earned in a lifetime, but then spending it all in a short period of time, and even becoming indebted. A country where the leaders are extravagant will surely perish, and a family will be the same. Therefore, even if a person is living in wealth and prosperity, they should still adhere to the traditional ethical values of thousands of years, be frugal, not be extravagant.
Not knowing contentment, even with wealth, it is difficult to be happy: Laozi said: "The contented are always rich, the greedy are always poor," meaning that knowing what is enough will never leave one lacking. Those who do not know contentment always feel lacking and will never succeed in finding true happiness. The material resources in this world are limited, but human desires are endless. Therefore, if a person truly wants to be happy and joyful, they must know how to control their own desires, know what is enough, and have good intentions. Knowing what is enough brings joy, not knowing what is enough leads to endless pursuit, fatigue, short life, and being surrounded by illness. A person's happiness is not because they have a lot, but because they are not calculating.
Not understanding the way of nurturing life, even with much treatment, it is difficult to live long: Treating illness before it arises is a great concept of ancient Eastern medicine. In the "Yellow Emperor's Inner Classic: Four Qi's Regulation and Great Discourse," it is written: "The sage does not treat a developed illness, but treats an illness before it arises; does not treat a disorder, but treats before a disorder arises." Treating an illness after it has formed is like treating a disorder, and treating a disorder after it has caused chaos is like digging a well when thirsty, forging weapons when the enemy is already present, isn't it too late? Instead of treating a severe illness after it has arisen, it is better to understand the way of nurturing life before the illness arises. The greatest way of nurturing life is not just nourishing and nurturing, but is actually cultivating one's character, cultivating the mind, accumulating virtue, and doing good deeds. When there is peace in the heart, health will also be nurtured.
