Democritus

By desiring little, a poor man makes himself rich.

Do not trust all men, but trust men of worth; the former course is silly, the latter a mark of prudence.

Word is a shadow of a deed.

Our sins are more easily remembered than our good deeds.

The pride of youth is in strength and beauty, the pride of old age is in discretion.

Tis hard to fight with anger, but the prudent man keeps it under control.

I would rather discover one scientific fact than become King of Persia.

Nothing exists except atoms and empty space; everything else is opinion.

Happiness resides not in possessions, and not in gold, happiness dwells in the soul.
