Happiness in adulthood may be determined by the quality of relationships in your youth, not brain power or academic prowess, new Australian research suggests.

“This shows that there is an enduring, significant relationship between being well-adjusted as a child and being well-adjusted as an adult,” said Dr. Victor Fornari, director of child/adolescent psychiatry at North Shore-LIJ Health System in New Hyde Park, N.Y. “(And) academic adjustment per se is not sufficient to lead to well-being.”

Learning the secrets of “the good life” has guided human endeavors for millennia. But according to study author Craig Olsson, an associate professor in developmental psychology at Deakin University and the Murdoch Children’s Research Institute in Melbourne, neither material wealth nor academic achievement has been strongly linked to happiness.
