Positive psychology focuses on human functioning, development, and success across the life dimensions (e.g. biological, personal, relational, institutional and cultural). To have complete mental health, a person must have a combination of high emotional, psychological, and social well-being, and low mental illness. Positive psychology aims to study the dimensions of life to develop those states of well-being, rather than focus on mental illness.
Positive psychology can be applied to many domains including organizational psychology, counseling and clinical psychology, business, health, education, and coaching.
