Really good art can be understood by everyone. There may only be a small group of people here, but they can really resonate with the artist, even if the artist just wants to do it at first. He is self-admiring, but human emotions are the same, and there will always be people with the same mood as him who will understand his works.
So if you think you are very talented, but the finished work is completely incomprehensible, and in the end you have a arrogant attitude that you are an artist and we are all mortals, and say " "You don't understand" are mostly people who are seeking fame and reputation. They are not self-admiring, but just sensationalizing.
The top artists in the world are very emotional beings. Their emotions are so strong and hot that they may even cross the moral shackles of the world. They are not understood or forgiven, and their moods often fluctuate.
The works are also very contagious and can easily convey their emotions at that time.
For example, Van Gogh's works have a great influence around the world. Although he was not understood by the world before his death, it was still proved after his death. He was a very emotional person. There are many rumors about Van Gogh's ears being cut off, but most of them said that he had his ears cut off because of a break with his best friend and his feelings for a prostitute.
Their emotions are often very extreme. When they cannot express them in words, they will resort to immersing themselves in artistic creation to resolve them. All works of art are the incarnation of the artist's emotions. It can be observed and received. There is no contradiction between self-appreciation and being understood by everyone. Artists are self-admiring when they create, but the results will be understood by everyone.
