This topic was chosen to mark the 45th edition of the international contest. Children around the world are warmly encouraged to give flight to their imagination , while writing a letter to themselves in the future. Our view of the world tends to change as we grow older, with the risk that the older person forgets or abandons the concerns and dreams of their younger self. The past becomes another country whose language we no longer speak.
Young people and children under 15 make up a quarter of the world's population, yet their voices are seldom heard. Perhaps this is because the 45-year-olds do not realise what important things they themselves once understood and how much of value young people have to say. In this year's competition, young writers are given the opportunity to reach across their own generation divide into the future. An important message can be sent before the language of youth is lost.
All member countries are invited to participate by organizing a competition on the national level before sending their top composition to the UPU. Each country's best letter must be submitted to the International Bureau no later than 30 April 201
