The fully functional person is a term introduced by American psychologist Carl Rogers, referring to a person who lives an ideal life. According to Rogers, a good life is a process and not a state of being. The process is characterized by achieving an increased openness to experience, a tendency to live fully in each moment, and an increasing trust in one’s own self.
