“Humans possess a hundred good traits and countless bad habits.” Vanity is one of the bad habits that people often fall victim to. Vanity, in simple terms, is the habit of being overly proud, self-centered, and self-evaluating one's own worth, always considering oneself as the center of the universe. 'Vanity' is a 'pernicious disease' where the afflicted individuals are constantly in a delusional state about themselves, always wanting to exaggerate the truth, boast, and strut to the point of absurdity. What they receive in return is only alienation, isolation, or even failure. In the past, when he was famous in the 'New Poetry' literary circle, Xuân Diệu wrote: 'I am One, I am Unique, I am the First/Nothing can be compared to me'. Later, after the August Revolution in 1945, the poet criticized this as the naive and superficial perception of youth. Indeed, youth is often passionate and impulsive, prone to self-delusion. Some talent or another hastily declares themselves the 'center of the universe'. I myself have also been arrogant about my own abilities, but the result I received was only failure. So, to overcome the vanity habit, we need to live humbly, be sociable, listen and share, constantly learn; dare to criticize and self-criticize, without hiding ignorance. Learn to be humble, and 'humility is a kind of moral virtue that corrects vanity.'

“What is vanity? Vanity is self-importance, self-grandeur, self-indulgence, evaluating oneself highly in front of others. Vanity is not knowing how to listen, unwilling to learn, always considering oneself above all others. People with vanity will grant themselves the “right” to not adhere to the rules, standards already established in the family, organization, or society. Two American researchers have stated: “While confident individuals tend to be more outgoing, sociable, and self-respecting, vanity is often associated with selfishness and shame. “A teacher is always proud of their teaching talent.” I remember, my uncle told me after interacting with a Japanese person, and that Japanese person said: “When ten Japanese have to fear one Vietnamese person, then one day in exams, ten Vietnamese will fear one Japanese.” In summary, “vanity” is a bad habit that always leads people to failure, being shunned by others. Why do people have the habit of “vanity”? Because the ego exists in everyone. Usually, the trait of “vanity” appears in talented, intelligent people. “He knows he's smart, talented, so he's very vain.” At the same time, due to inappropriate, inaccurate cognitive level, leading to the phenomenon of overestimating one's own achievements in the overall harmony of family, organizational, or societal relationships. No one's life is perfect, everyone has experienced it at least once in their lifetime. Have you ever asked: “A powerful country, advanced in technology like the United States, has not achieved victory in invading our Vietnam yet?” A powerful country like the United States always has a haughty, vain attitude, always considering itself victorious, never failing, and so the United States has incurred defeat.'

Vanity can be simply understood as arrogance, where individuals have delusions about themselves, always thinking they are the best, disregarding many people around them. In other words, vanity is also arrogance, self-importance, and self-indulgence, where individuals have elevated themselves in front of many others. Those with vain personalities often consider themselves entirely entitled not to follow the rules, standards set and readily available within the family, organization, or society. Vanity also involves individuals always considering themselves skilled and not listening to advice when others have suggestions, stubbornly believing they are right. In other words, vanity is also excessively high self-confidence of each individual, to the point of blurring the willpower and perception of each individual. Those with vain personalities often make others uncomfortable because these subjects often feel lonely, isolated. While self-confidence can lead us to success, vanity will lead us to failure. With a vain person, they often cannot see others' talents and will not broaden their knowledge or gain more experience; instead, they will always think they are the best, so failure is understandable. Because, nowadays, in life, if we are skilled, there will always be others around us who are more skilled, so every individual needs to constantly improve their knowledge and skills to not be left behind.

Vain individuals are often very emotional. They make superficial judgments about situations or circumstances solely based on feelings, perceptions, and appearances. They consider themselves right. And the end result often doesn't turn out as desired. For example, Lü Bu is a typical vain person. When Cao Cao's army approached sincerely, in the face of the overwhelming enemy, Lü Bu remained arrogant in front of Diaochan: “You don't need to worry too much. I have the Sky Piercer, the Red Hare, who dares to come near me?” Vain people tend to overestimate their abilities without considering their limits, without self-awareness. Some overestimate themselves, like to elevate themselves and look down on others. They always think they are better than others. Some are stubborn, insistently thinking they are right. Always impose their views on others. Even knowing that others are right, they refuse to change themselves. Vain, arrogant people often don't care about others. And they distance themselves from others. They often only care about their own interests, ignoring others. They are indifferent and cold to others. In conclusion, arrogant and vain individuals are very prone to exaggerating themselves for minor achievements. Once like this, they will quickly lose direction. Bringing the gap between themselves and failure closer.
