1. Know yourself through self-observation. Our understanding of our various physical and mental states and interpersonal relationships, namely, physical self, psychological self and social self. For example, their own height, appearance, posture, personality, their relationship with others and other aspects of understanding. In the process of self-knowledge, there are emotional experiences, such as pride, self-confidence or inferiority caused by height and appearance. Moreover, in the process of self-knowledge and self-emotional experience, do we intentionally and consciously adjust and control our behaviors and ideas? We should be good at analyzing ourselves, deeply understanding ourselves and better understanding the external image and internal self.

2. Know yourself through other people's evaluation. We all know that "bystanders see clearly" and "taking people as a mirror can understand gains and losses". In the process of knowing yourself, you should take the initiative to know yourself from others. We should listen to others' comments with an open mind, and at the same time analyze others' comments objectively and calmly, so as to know ourselves from multiple angles.

3. Know yourself better through social comparison. Self-observation and others will inevitably have their own subjective projections, so we can better understand ourselves through a reasonable society. We compare ourselves vertically with the past and the future, horizontally with people of the same age or similar conditions, and correctly understand ourselves through a more comprehensive vertical and horizontal social comparison.

4. Know yourself through social practice. We can know ourselves by participating in various activities and according to the process and results of various activities. Analyze one's interpersonal skills by cooperating with others, analyze one's organizational management skills by organizing activities, discover one's mastery of knowledge through reading activities, and timely check for missing information. Analyze your performance and achievements through specific activities, and get to know yourself more objectively.

5. Know yourself through reflection and summary. We find that in the above four steps, we are all discovering and knowing ourselves. Many people are like this, but we still don't know what kind of person we are, so we still need to reflect and sum up ourselves frequently. Keep more diaries to record yourself, sum up your advantages and disadvantages in time, and better grasp your physical self, psychological self and social self.
