This little book of hygge came about after a particularly hyggeligt evening in December 2015. I had just lit my pleasing contemporary wood-burner and was sitting back, gløgg in hand, listening to Terj Dørk's classic drøn jazz album "Tepid in Taarstrup'. I found myself reflecting on the fact that we are the World's Happiest PeopleT. Wasn't it time, I thought, we shared our secret? I immediately called around three of the Institute of Wellbeing's brightest young researchers: Freja, Olaf and Sofia. We sat together snug in my pure wool foursie, bathed on soft fire-light, and talked long into the evening. The idea came over us unexpectedly. We would publish a book, explaining hygge for the betterment of all mankind. I'm delighted that we have succeeded. And I hope our efforts will help you to find your own hygge-topia. Held og lykke!
