Smiling and cheerful teens are likely to earn more money than morose adolescents when they grow up, according to a study.
The study of 15,000 adolescents and young adults discovered a one-point increase in life satisfaction - another term for happiness, on a scale of five - at the age of 22 is associated with almost 2000 dollars higher pay a year at the age of 29, the Daily Telegraph reported.
Even in siblings, the happier teen went on to earn more than their less cheerful brothers or sisters, the study carried out on American teens found.
Dr Jan-Emmanuel De Neve from University College London and Professor Andrew Oswald from the University of Warwick, found that happy individuals'' greater wealth is due partly to them being more likely to get a degree, a job and get promoted faster than their gloomier counterparts.
These findings show that the emotional well-being of children and adolescents is key to their future success, Dr De Neve said. (ANI)
