"This model aims to explain how and why performing positive activities makes people happier. As illustrated at top, positive activities increase positive emotions, positive thoughts, positive behaviors, and need satisfaction, all of which in turn enhance well-being. Features of positive activities (e.g., dosage and variety) and of the person (e.g., motivation and effort) influence the degree to which the activities improve well-being.
