It’s been said many times that you can’t buy happiness with money. The Washington Post runs the article about the research that begs to differ:
Not only did the extra income appear to lower the instance of behavioral and emotional disorders among the children, but, perhaps even more important, it also boosted two key personality traits that tend to go hand in hand with long-term positive life outcomes.
The first is conscientiousness. People who lack it tend to lie, break rules and have trouble paying attention. The second is agreeableness, which leads to a comfort around people and aptness for teamwork. And both are strongly correlated with various forms of later life success and happiness.
