David Brooks writes;
If the relationship between money and well-being is complicated, the correspondence between personal relationships and happiness is not. The daily activities most associated with happiness are sex, socializing after work and having dinner with others. The daily activity most injurious to happiness is commuting. According to one study, joining a group that meets even just once a month produces the same happiness gain as doubling your income. According to another, being married produces a psychic gain equivalent to more than $100,000 a year.
If you want to find a good place to live, just ask people if they trust their neighbors. Levels of social trust vary enormously, but countries with high social trust have happier people, better health, more efficient government, more economic growth, and less fear of crime (regardless of whether actual crime rates are increasing or decreasing).
