I used research to try to understand why the Norwegians are the happiest people, the inhabitants of Latin America are the most resilient, the Japanese are on the top of the list for life expectancy, and the Finns are called the freest nation. As it turned out, these cultures are happy thanks to the simple everyday things, such as cleaning and organizing their lives and their relationship to garbage and nature. I tried to derive the formula of happiness project, having collected a plethora of information on happiness, freedom, and joy in different countries of the world. I understand that the keys to happiness are hidden in every house. You can find happiness in creating a life, doing household chores and, of course, cleaning up. This is the first step in understanding that happiness is near. I tried to reveal this mystery by studying the philosophy of everyday life in different countries, which every year turn out to be the leaders in the ratings for the "happiest" and "most cheerful countries". Perhaps this book will be a useful tool for those who have already realized that the keys to happiness are hidden in their homes. Will you find them after spreading things on the shelves, changing the interior, and adjusting your attitude toward cleaning?
