Happiness depends upon ourselves.

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

One swallow does not make a summer, neither does one fine day; similarly one day or brief time of happiness does not make a person entirely happy.

Happiness is a state of activity.

Happiness is a quality of the soul...not a function of one's material circumstances.

All human happiness or misery takes the form of action; the end for which we live is a certain kind of action.

Happiness does not lie in amusement; it would be strange if one were to take trouble and suffer hardship all one's life in order to amuse oneself

The happy life is thought to be one of excellence; now an excellent life requires exertion, and does not consist in amusement. If Eudaimonia, or happiness, is activity in accordance with excellence, it is reasonable that it should be in accordance with the highest excellence; and this will be that of the best thing in us.

True happiness flows from the possession of wisdom and virtue and not from the possession of external goods.
