This is the meaning of being a gentleman:
Be polite-a gentleman is impeccable in any situation. He makes others feel comfortable. He knows when to be quiet and when to talk. He is a good host and guest. While keeping honest, he didn't impose his views on others. If his point of view doesn't agree with people in public places, he will politely say no and leave it there.
Well-educated people-gentlemen are well-read in many parts of the world. He knows a lot about science, technology and history.
Be good at listening-a gentleman will pay close attention to everything the other person says. He tried his best to understand different viewpoints. Even though he totally disagreed with other people's opinions, he showed respect.
Self-sufficiency-A gentleman rarely (if ever) asks anyone to help him financially. Ideally, after a gentleman reaches a certain age (such as 30 or 40), he doesn't need to borrow money for any reason.
There is a respectable profession-a gentleman will avoid promoting bad habits. This will include any occupation related to gambling, pornography, junk food, unintentional entertainment and illegal (or suspicious) drugs.
Always care about your appearance-a gentleman is always perfectly decorated in public. Wash your hair, comb your hair and have a professional hairstyle. Manicure. Facial hair is either completely shaved or trimmed very neatly and meticulously. He has no obvious nose hair or ear hair. There are absolutely no cracks and stains on his clothes. Clothes should not be too tight or too loose.
Taste-A gentleman knows the meaning of taste. He knows the colors and styles suitable for clothes, cars and furniture. A gentleman will never be attracted by flashy styles and colors. He is subtle and gentle-he never attracts unnecessary attention.
Educated-A gentleman knows something about the history of art, music, religion, philosophy and literature. He is familiar with the classics of his own culture, at least with some classics of other cultures.
Have an aim in life-a gentleman always knows what he wants from life. He said to "What do you want from life?" There is an answer to this question. He has a sense of purpose, meaning and direction. He is willing to share his life goals with others.
Never lose your composure-perhaps the most important sign of being a gentleman is to control your emotions. A gentleman never raises his voice unless there is imminent danger. He kept calm in the face of an emergency. In the face of insults, he remains firm and strong. He never intended to get back at anyone. When others become irrational and emotional, a gentleman is the kind of person who seeks leadership.
