School is the alternate home of a Child. A child learns basic steps of life to grow as a man in the school. In rough terms, we can say that School is the factory to produce components of the Society. A Nation is recognized by its modern and flourished societies. The best societies are made by the contribution of well educated and intellectual people.
A man is build up with the foundation of education he got in his school. He is going to contribute the society by applying the knowledge and wisdom in appropriate place, which he acquired in his student life. The quality of education matters in this regard because he will be performing according to the level of education he got.
We can map a school as the breeding ground for the quality production of a Man. A man is born with a blank mind; School is responsible to feed the brain with quality input to help him to grow as a responsible citizen of a Nation. That's why today's parents want to educate their child in the best possible environment. To build a Great Nation the contribution of each and every responsible citizen is precious.
An Ocean is a collection of numerous number of tiny water droplets, similarly a Nation is a collection of numerous responsible citizens. To make it developed, each member of it should be well-educated and intelligent enough to fight against any kind of odd situation. School makes it possible to groom an infant child to a great man to be a part of such Society.
