In order to be happy oneself it is necessary to make at least one other person happy. . . . The secret of human happiness is not in self-seeking but in self-forgetting.”

“A day without laughter is a day wasted.”

“Happiness can be found even in the darkest of times, if one only remembers to turn on the light.”

“The talent for being happy is appreciating and liking what you have, instead of what you don't have.”

“The world is full of a number of things, I'm sure we should all be as happy as kings.”
