When I think about happiness in Poland, two things come to my mind.
First of all, in Poland there is a village called 'Szczęście' ('Happiness). I strongly believe that people who live there are very happy :)
Secondly, for me happiness is strongly connected with a smile. In Polnad there is 'Muzeum Orderu Uśmiechu' ('Museum of smiling order'). It is a special award which is given by children for adults. The Museum is situated in Rabka - Zdrój, in an Amusement Park for families called Rabkoland. The city is also called 'the city of children from all over the world'. The ceremony is always very solemn. In my opinion it is a great opportunity for children to give an award to meritorious people. They feel very responsible and proud of their choices. What's more, it's also a charitable foundation, and that's the most important role of it.
Enjoyment and help = that's for me the definition of happiness.
