True happiness is not attained through self-gratification, but through fidelity to a worthy purpose. Helen Keller
You will never be happier than you expect. To change your happiness, change your expectation. Bette Davis
Hope is itself a species of happiness, and, perhaps, the chief happiness which this world affords. Samuel Johnson
Happiness is man’s greatest aim in life. Tranquility and rationality are the cornerstones of happiness. Epicurus
He taught that the point of all one’s actions was to attain pleasure (conceived of as tranquility) for oneself, and that this could be done by limiting one’s desires and by banishing the fear of the gods and of death. Epicurus’ gospel of freedom from fear proved to be quite popular, and communities of Epicureans flourished for centuries after his death.
