Happiness Formula

According to Harvard psychologist Dan Gilbert,

Happiness = marriage, money, and no children

1. Marriage: People in good marriages are happier, healthier, and live longer than unmarried 
2. Money: Some money buys a lot of happiness, a lot of money only marginally increases it ... with the golden per capita income hovering between $50,000 to $75,000. Richer people can increase happiness by staying active and spending their wealth on others.
3. Children: childless couples are happier than their counterparts
