“Optimism is the one quality more associated with success and happiness than any other. ”

“I am struck by how sharing our weakness and difficulties is more nourishing to others than sharing our qualities and successes.”

“It is the deep, salty stickiness of food that intrigues me more than any other quality.”

“I do not think there is any other quality so essential to success of any kind as the quality of perseverance. It overcomes almost everything, even nature.”

“There are more worlds than one, and in many ways they are unlike each other. But joy and sorrow, or, in other words, good and evil,are not absent in their degree from any of the worlds, for wherever there is life there is action, and action is but the expression of one or other of these qualities.”

“The fact that a believer is happier than a skeptic is no more to the point than the fact that a drunken man is happier than a sober one. The happiness of credulity is a cheap and dangerous quality of happiness, and by no means a necessity of life.”
