How to make the world a better place

My son is doing a biography on Mother Teresa. I think her ideas of making the world a better place are so right, and simple. When she received the Nobel Peace Prize in 1979 they asked her how we can promote world peace. Her answer was simple, "Go home and love your family."
In her Nobel Lecture some of her quotes are:

" Love begins at home, and it is not how much we do, but how much love we put in the action that we do. It is to God Almighty - how much we do it does not matter, because He is infinite, but how much love we put in that action. How much we do to Him in the person that we are serving."

"You too try to bring that presence of God in your family, for the family that prays together stays together. And I think that we in our fmaily need to just get together, love one another, bring that peace, that joy, that strength of presence of each other in the home. And we will be able to overcome all the evil that is in the world."

"I want you to find the poor here, right in your own home first. And begin love there. Be that good news to your own people. And find out about your next-door neighbour - do you know who they are? And you see this is where love begins - at home."

"You must come to know the poor, maybe our people here have material things, everything, but I think that if we all look into our own homes, how difficult we find it sometimes to smile at each other, and that smile is the beginning of love. And so let us always meet each other with a smile, for the smile is the beginning of love, and once we begin to love each other naturally we want to do something"

"Let us keep that joy of loving Jesus in our hearts. And share that joy with all that we come in touch with. And that radiating joy is real, for we have no reason not to be happy because we have Christ with us. Christ in our hearts, Christ in the poor that we meet, Christ in the smile that we give and the smile that we received."

"If we could only remember that God loves me, and I have an opportunity to love others as He loves me, not in big things, but in small things with great love."

I truly believe and agree that it's not in the big things, but in the small things (or so we perceive them to be small things) that bring joy, peace, laughter. A smile to a stranger, a smile to your family and friends, a kind word, a helping hand, a phone call or card when someone is hurting, prayer for those in need, being polite and kind to people you meet at the store, school, in your daily travels. I think if we were all to try and do this everyday our world would be a better place.
