Description :-

The Little Book of Hygge : The Danish Way to Live Well

Hygge has been described as everything from "cosines of the soul" to "the pursuit of everyday pleasures". The Little Book of Hygge is the book we all need right now, guaranteed to bring warmth and comfort into your life.

The Little Book of Lykke : The Danish Search for the World's Happiest People

It's easy to see why Denmark is often called the world's happiest country. Not only do they have equal parental leave for men and women, free higher education and trains that run on time, but they burn more candles per household than anywhere else.

The Art of Making Memories: How to Create and Remember Happy Moments 

In The Art of Making Memories he brings together his extensive research drawn from the world's biggest study on happy memories (which involved 1000 people from 75 countries), conducted at the Happiness Research Institute, along with data and diaries, interviews, global surveys and studies, and real-life behavioural science and happiness experiments, to explain the nuances of nostalgia, the different ways we form memories around our experiences, and how we can become better at recalling them.
