"The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well."
Ralph Waldo Emerson
I like this quote.
And this story...
Starfish
One day, a man was walking along a beach.
He noticed a young boy who was reaching down, picking up small objects and throwing them into the sea.
As he got closer, he called out "Good morning. May I ask what you are doing?"
The young boy paused, looked up and replied "Throwing starfish into the sea."
The man bewilderedly asked "Why are you throwing starfish into the sea?"
To this the young boy replied "The sun is up and the tide is going out. If I don't throw them in, they will die."
Hearing this the man said "There are miles of beach and there are starfish along every mile. You can't possibly make a difference."
At this, the young boy bent down, picked up another starfish and threw it into the sea. As it met the water, he said "Well, it made a difference for that one."
