Self-awareness, if explained in psychological terms, is to realize the content of the subconscious. Once the contents of the subconscious "black box" hidden behind the values, beliefs and dogmas you take for granted are illuminated by the light of self-awareness, some irrational things that once controlled you can disappear.
In this regard, the German philosopher Nietzsche also said a famous saying: "People who know why they are alive can almost overcome all kinds of problems."
