“I believe that if at the end of it all according to our abilities we’ve done something to make others a little happier and something to make ourselves a little happier, that is about the best we can do.  To make others less happy is a crime; to make ourselves unhappy is where all crimes start. 
We must strive to contribute joy to the world.  That is true no matter what our problems, our health, our circumstances, we must try. I didn’t always know this and I’m happy that I lived long enough to find it out.”
