CHILO (fl. 560 B.C), Greek sage

Friendship
Be more prompt to go to a friend in adversity than in prosperity.

Gold
As the touchstone tries gold, so gold tries men.

Honesty
Prefer loss before unjust gain: for that brings grief but once; this forever.

Wealth
Prefer loss to the wealth of dishonest gain; the former vexes you for a time; the latter will bring you lasting remorse.
