What is the connotation of self-consciousness in psychology? What are the four important pillars of a healthy self-awareness?

According to the theory of perceptual growth model, self-awareness is self-awareness of itself, the relationship with others and the surrounding environment. According to the definition of self-awareness, it includes self-awareness unit (that is, self-awareness unit) and self-awareness unit of the relationship with others, surrounding things and environment. However, how can there be a perceptual unit for their relationship without a perceptual unit for others and things around them? Therefore, self-consciousness is essentially the sum total of the above-mentioned complex and numerous perceptual units, and they develop through mutual infiltration in the process of development. The core of self-awareness is the unit of self-awareness. The self-perception unit includes the perception of one's own physiological and psychological characteristics, as well as the perception of one's independence from others and the external environment.
