In front of excellence, the immortal gods have put sweat, and long and steep is the way to it.
HesiodDo not let any sweet-talking woman beguile your good sense with the fascinations of her shape. It's your barn she's after.
HesiodEvil can be got very easily and exists in quantity: the road to her is very smooth, and she lives near by. But between us and virtue the gods have placed the sweat of our brows; the road to her is long and steep, and it is rough at first; but when a man has reached the top, then she is easy to attain, although before she was hard.
Hesiod
