Abstract 

The article outlines the predicting effects of the self-congruence, attachment,  stress, anxiety, depression, and happiness, on flourishing. The differentiation  of social roles and life domains is included as a supposed pathway to flourishing  and well-being promotion. 359 volunteers completed self-congruence, stress, anxiety and depression, relationships, happiness, differentiation and  flourishing self-reporting scales and incomplete sentences on the daily way  they differentiate their life domains and social roles as a form of preventive  and proactive coping. In the hierarchical model, the accounted flourishing  dispersion is 84% with predictors’ differentiation, happiness, low depression  and relationships avoidance. In addition, the main effect of differentiation on  both flourishing and all its predictors is reported. This leads to the conclusion  on the importance of interventions to equip individuals with good differentiation  abilities throughout life cycle.
