For the last six years, Finland has been ranked the happiest country in the world. I've lived here most of my life, and as a psychologist and happiness researcher, I'm often asked: what exactly makes people in Finland so satisfied with their lives?

You may be surprised to learn that Finnish people are often the first to question this characterization. Our national self-image is that we're quiet, introverted and somewhat melancholy types. This doesn't exactly align with being the happiest people on earth.
