"One day, when I am old, I shall sit by the fire and remember that I have been happy."

"One must have loved, to know what it is to live."

"The best way to make a man happy is to give him a chance to be generous."

"There is neither happiness nor misery in the world; there is only the comparison of one state with another, nothing more."

"The happiness of your life depends upon the quality of your thoughts."
