The so-called genius, I understand, is unyielding to external forces and acting according to his own nature. He always loves to realize his own value in the initiative of the subject, and find a beauty of creation, performance, self-pleasure and self-appreciation. This beauty is mainly reflected in a kind of primitive vitality, a non-utilitarian ID manifestation, which is not related to the success, fame and wealth in the sense of custom, disobedience to the golden mean. 
Genius is a great creator, sick and weird.
 in the eyes of the secular world, genius is morbid and weird: for the social structure and group order, genius is a heretical and unstable factor. The creative process of genius is a wrestling process of repression and anti-repression, resistance and obedience, degeneration and sublimation with both internal and external circles.
