Euripides

One does nothing who tries to console a despondent person with word. A friend is one who aids with deeds at a critical time when deeds are called for.

Whoso neglects learning in his youth, loses the past and is dead for the future.

No one is truly free, they are a slave to wealth, fortune, the law, or other people restraining them from acting according to their will.

Wealth stays with us a little moment if at all: only our characters are steadfast, not our gold.

Nothing has more strength than dire necessity.

In misfortune, which friend remains a friend?

Ignorance of one's misfortunes is clear gain.

The bold are helpless without cleverness.

Events will take their course, it is no good of being angry at them; he is happiest who wisely turns them to the best account.

Danger gleams like sunshine to a brave man's eyes.

Love makes the time pass. Time makes love pass.

Twas but my tongue, 'twas not my soul that swore.
