Which comes first, happiness or money? Are richer people happier? And if so, how do people get much richer? A recent study could tell you the answer.
The study looked into thousands of teenagers and found that those who felt better about life as young adults tended to have higher incomes by the time they turned 29. Those who were happiest earned an average of $8,000 more than those who were the most depressed.
The researchers, from University College London and the University of Warwick, say that very gloomy teens, no matter how tall or smart they were, earned 10% less than their peers, while the happier ones earned up to 30% more.
Happier teenagers have an easier time getting through school, college and a job interview, chiefly because they always feel better about life. It may also be true that happier people find it easier to make friends, who are often the key to homework help or networking.
A report in June suggested that professional respect was more important than dollars in terms of workplace happiness. In August scientists announced that they had found the gene for happiness in women, Alas （the same gene doesn’t appear to have the same effect on men）. And in October researchers in the UK and in the US announced that people who eat seven portions of fruit and vegetables a day report being the happiest.
The big question is: if it really is true that happier kids end up being wealthier kids, is it necessary for parents to get their kids to do the homework? The fact is that no homework will make kids happy but surely hurt their grades. Studies do show, after all, that more education leads to better-paid jobs, which may give us a deep thought.
“These findings show that the teenagers’ happiness is important to their future success,” one of the report’s authors writes. “But what is the most important is that we should find a way to help children gain more satisfaction from doing schoolwork.”
