People with good outlooks, stemming from a positive upbringing, may make more money than folks with a less positive view of themselves. A study published in the National Academy of Sciences found that people who are already happy due to a positive childhood tend to make more money as adults.
The study followed more than 15,000 from 1994 to 2008. The subjects included twins and siblings that were not raised in the same household. The 14-year study came to its conclusions based on the number of times respondents indicated by response that they enjoyed life; they were happy; and that they felt just as good as other people.
After following the participants for 14 years, the study found a clear link between a satisfying childhood and a higher salary as adults. Some of the reasons the researchers believe that happier children go on to become more successful is due to their positive, outgoing attitude and their greater likelihood of getting hired, promoted and earning a higher degree.
