Researchers at Princeton's Woodrow Wilson University have shed light on a long-discussed topic about the relationship between money and happiness.

The study found a correlation between earnings in U.S. dollars on the one hand, and the highest level of happiness achieved. According to the study, if people start earning more and more, happiness increases accordingly. However, as soon as the level of income reaches $75,000 per year, holders of such earnings stop feeling happier.
Each person feels happiness differently. For some, happiness is success achieved. But success, like happiness, also comes with a price. A recent survey on CareerBuilder found that 49% workers earning a salary of $70,000 or more feel successful. These studies show that with an income of about $75,000, an American is quite happy. There is a list of seven fastest-growing jobs in the U.S. that pay about $75,000 a year.

1. Financial Expert
2. health and safety, engineer
3. Hydrologist
Information Security Analyst, Web Developer and Computer Network Architect
5. Medical scientists
6. Physiotherapist
7. Radiation rehabilitation therapists
