This conclusion presents some closing thoughts on the concepts discussed in the preceding chapters of this book. The book discusses the differences in health conditions, material resources, exposure to social norms, conflicting role expectations and freedom of choice that the reasons for the differences in happiness and unhappiness can be well described by factors of relevance for Mathews' and Izquierdo's four-dimensional model of happiness. It also discusses the four dimensions of well-being is more influential throughout the life course and how each domain is related to the turning points in the life course and broader social change. The book provides evidence for reproduction of normative life plans by consecutive generations of homemakers, continuities of peer group expectations across the generations and the intergenerational transfer of cumulative advantages in the context of "promise of female happiness".
