“Happiness is a quality and an attribute of the good life. The more you try to define it the less you know about it. It is as ineluctable as electricity, as evanescent as melody, as indefinable as health, as variable as speed, time, matter, and the other fictions on which life itself is built. Happiness knows no standards and no limits.”

“It's not what happens to you, but how you react to it that matters.”

“The happiness which is lacking makes one think even the happiness one has unbearable.”

“Be happy. Talk happiness.”

“Satisfaction of one's curiosity is one of the greatest sources of happiness in life.”

“Happiness is the interval between periods of unhappiness.”

“It is only to the happy that tears are a luxury.”
