Gallup has a nifty survey about happiness. They made a list of characteristics that correlate with happiness. The New York Times put these characteristics together and set out to find a person who embodied them. A married father, Chinese-American, observant Jew, successful in business - in Hawaii.
They found him, through a Honolulu synagogue: Alvin Wong.
What stands out to me in this list are the several factors that strengthen meaningful purpose in life. The core element, I think, is being a married father. Chinese Americans, and observant Jews, are both subcultures that strongly support married fatherhood. The successful business flows from sticking to the purpose of supporting your family with work, the more meaningful the better.
Hawaii is just a bonus.
