"Spread love everywhere you go: first of all in your own house. Give love to your children, to your wife or husband, to a next door neighbor... Let no one ever come to you without leaving better and happier. Be the living expression of God's kindness; kindness in your face, kindness in your eyes, kindness in your smile, kindness in your warm greeting."
We ourselves feel that what we are doing is just a drop in the ocean. But the ocean would be less because of that missing drop.
