Be slow to undertake any enterprise; but persevere steadfastly in whatever you undertake.
Do not rush to speak, for this is a sign of madness.
Love wisdom.
As concerns the gods, say that they exist.
If a man is unworthy, do not praise him because of his wealth.
Prevail by persuation, not by force.
Attribute to the gods whatever good you do.
Take wisdom as your provision from youth to old age, for it is more dependable than all other provisions.
His maxim is: Most men are bad.
Diogenes Laertius - Lives of the eminent philosophers
