The project is 2-year partnership between 5 secondary schools from Poland, the Czech Republic, Romania, Lithuania and Greece. It is designed in a way teachers and students can broaden the knowledge of happiness and learn about ways of achieving and maintaining happiness in order to improve the quality of life. We will focus on: What is happiness? How to become happy? How to overcome stress? What are the risks of our interference with the natural environment that affect our experiencing of happiness? How to become promoters of personal development and global change regarding the environment, staying both eco and happy?
