To you, foolish Perses, I will speak good sense. Badness can be got easily and in shoals: the road to her is smooth, and she lives very near us. But between us and Goodness the gods have placed the sweat of our brows: long and steep is the path that leads to her, and it is rough at the first; but when a man has reached the top, then is she easy to reach, though before that she was hard.
