Step-by-step explanation:
The statement is true. When there is a contradiction between the ideal self and the real self, personality problems can occur. Carl Rogers, a humanistic psychologist, proposed the concept of self-concept, which involves the ideal self (the person one would like to be) and the real self (the person one actually is). Rogers believed that achieving consistency between these two selves, or congruence, is important for a healthy and productive life.
