All happiness or unhappiness solely depends upon the quality of the object to which we are attached by love.
Friendship improves happiness and abates misery, by the doubling of our joy and the dividing of our grief.
HAPPINESS, FRIENDSHIP IMPROVES HAPPINESS
The happiness of this life depends less on what befalls you than the way in which you take it.
HAPPINESS, LIFE DEPENDS LESS ON WHAT BEFALLS
Happiness is beneficial for the body, but it is grief that develops the powers of the mind.
