No one knew India has the largest youth than any other country which means a huge power of ignition ... every young man could achieve something in his life but self exploration is important and  we people are not exploring ourselves and just pulling our life till the should mention nation's  greatest man ever Dr. APJ Abdul kalam who strived for the betterment of youth in India and tried to put them in right path.. must take him as an inspiration..We must unite to CHANGE to change ourselves, our society, our nation, our world ...We must CHANGE for A NEW WORLD and this change should come from me must be ur feeling because this world is too much fast to blame others..We see many people say we r youth but what u did for the country??? for the world being a human we must do something.. so let's change for a new world..

What is meant by "society”?
Society is a long standing group of people sharing cultural aspects such as language, dress, and norms of behaviour, artistic forms and thoughts.
What is meant by the word "welfare"?
Well, welfare means health, safety, happiness, and prosperity. These are what we all want to have in our life. We want the best for our society .we want to make it a place having all these qualities.
How welfare of my society depends on my well being?
People living in the society always think that if the society changes then the other people living in it would also change. This is a very wrong thought. A class can never be called a good one until and unless all the students in it studies and behaves well. The same applies for our society and the people living in it. Unless the people start to live a life full of happiness, love, safety and prosperity, the society can never progress.

I need to change myself first. I have to be a good person and be loving, caring and helpful to others. I cannot be rude to others and expect others to be kind to me. This is not possible. We all know that, “as we sow so we reap”. If I start the change just as sowing a seed then automatically others would follow me and gradually the whole society would change and become the best one just as a big and strong tree. When other societies would see this change in my society then they would also soon try to improve themselves which in turn would improve the whole society. This is how the welfare of my country depends on my well being.
