Happiness can lead to success, rather than just the other way around. Happy individuals are predisposed to seek out new opportunities and set new goals. After reviewing data of 225 studies gathered from more than 275,000 individuals, a team of psychologists concluded that while previous research assumed that happiness stemmed from success and accomplishment, happiness is often a result of positive emotions. Success is the result of many factors, including physical health, intelligence, family and expertise.
