In the past, it was not thought that children would be the creators of the country. In any case, from now on, this view will change. Teenagers are the future who will control and run the world at some point in the future. So young people make up a significant part of the public eye. What they do, what they achieve, what they are presented to influence our future and the ultimate fate of society at large. The strong development of a country in the future depends on the age of youth. As teenagers, we have a responsibility to everyone in the future. If we don't change ourselves, how will the improvement in society take place?
