Happiness is activity

Happiness is the highest good, being a realization and perfect practice of virtue, which some can attain, while others have little or none of it

Happiness is a sort of action

Happiness seems to require a modicum of external prosperity

The virtue of justice consists in moderation, as regulated by wisdom

William Butler Yeats

Happiness depends upon ourselves

Happiness belongs to the self-sufficient

Happiness is the meaning and the purpose of life, the whole aim and end of human existence

Quality is not an act, it is a habit
