Being uncertain and insecure about one's perception of oneself might lead to failure or a lack of interest in life. Understanding oneself and the kind of person one wants to be is crucial. To develop a positive self-concept, one must first have self-awareness.
There is a difference between self-concept and self-understanding, despite popular belief to the contrary. A person's self-concept is made up of all of their behaviors, convictions, and skills, as well as what they infer about themselves from other people's reactions. The capacity to comprehend oneself includes the capacity to comprehend one's own actions, reactions, and behaviors.
