New book by the founder and director of the Institute for the Study of Happiness in Copenhagen, author of the best-selling books "Hygge. The Secret of Danish Happiness" and "Lykke. In search of the secrets of the happiest people." Do you remember your first kiss? And your first day of school? Or how do the first rays of the spring sun feel on your face? And what was the most delicious dish you tried? Why does music, smell, taste suddenly return us to some moments that we seemingly forgot about long ago? Is it possible to learn to create and maintain happy memories that will bring us joy for many years to come?
