"The greatest events of history are often brought about by the most trivial causes."

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

"All generalizations are dangerous, even this one."

"The sum of all villainies is to deceive oneself."

"Often we pass beside happiness without seeing it, without looking at it, or even if we have seen and looked at it, without recognizing it."
