We must be doing something to be happy.

The action is best that secures the greatest happiness for the greatest number.

Action may not always bring happiness, but there is no happiness without action.

Even in the common affairs of life, in love, friendship, and marriage, how little security have we when we trust our happiness in the hands of others!

Action may not bring happiness but there is no happiness without action.

Action and personal happiness have no truck with each other; they are eternally at war.
