There are five main types of personality: conscientiousness, extroversion, agreeableness, openness to experience, and neuroticism. There are also six types of personality disorders: paranoid, schizoid, schizotypal, antisocial, borderline, and histrionic. Humanistic psychology views personality as connected to inner feelings and self-image. The ancient Indian model sees personality developing through five "sheaths" nourished by different things like food, bioenergy, education, ego, and emotions. Developing personality in primary and secondary school focuses on building confidence, intellectual skills, respect, and values through activities, workshops, group discussions, and lessons in various subjects.
