Beyond that, the people who tended to have “happy-well” outcomes were conscientious, emotionally healthy individuals who set and actively pursued goals; who incorporated strong social networks, exercise and “healthy” eating/drinking habits organically into their everyday lives; who were optimistic but not to the point of being careless or reckless; social enough to form strong networks, but not so social as to pursue unhealthy habits for peer approval; and who felt engaged and satisfied in their careers, marriages, and friendships.

Lots of interesting ideas in the article beyond this point.
