Many of us work far too hard at jobs with people we don’t like -not a likely path to happiness. Dr. MacKerron and the economist Alex Bryson found that work is the second-most-miserable activity; of 40 activities, only being sick in bed makes people less happy than working. The economist Steven Levitt found that when people are uncertain whether to quit a job, they can be nudged to quit. And when they quit, they report increased happiness months later.

People get a big happiness boost from being with a romantic partner or friends. Weather plays only a small role in happiness, except that people get a hearty mood boost on extraordinary sunny days. People are consistently happier when they are out in nature, particularly near a body of water and particularly when the scenery is beautiful. >>>
