In a study of more than 10,000 Americans, those who experienced more positive daily emotions and felt more satisfied with their lives while growing up earned more income by age 29, according to research from University College London and London School of Economics professor Jan-Emmanuel De Neve and University of Warwick economics professor Andrew Oswald.
They pulled data from a 15-year period of surveys about happiness and then checked in on their pay later in life. On the 1-5 scale the researchers use, a happiness point increase by age 22 brought in an extra $2,000 a year later. People with a “profoundly unhappy” childhood made 30 percent less than average.
