Those who know themselves are the realm of life
The realm of self-knowledge meant that if a person had self-knowledge, he would be able to recognize his own strengths and weaknesses, clarify his own goals and direction, and work hard for it. This was considered a higher realm of life. Self-knowledge meant that one understood one's own value and ability, not blindly pursuing recognition and praise from the outside world, but rather setting goals and plans based on one's actual situation and ability level, and continuing to work hard for them. This kind of attitude could make people more confident and firm, avoid blind and hesitant situations, and make people cherish their time and opportunities more to create better results. The realm of life referred to the height and depth that people reached in their lives, including thoughts, morals, emotions, behavior, and so on. Those with self-awareness would be able to realize their own realm level and constantly strive to improve their abilities and qualities to reach a higher realm in life, so as to obtain more gains and achievements in life.
