A man has no enemy worse than himself.

While the sick man has life, there is hope.

Men of different tastes have different pursuits.

An old man with something of the youth in him, may feel young in mind and heart only.

Let every man practise the trade which he best understands.

Let each man have according to his deserts.

It is fortune, not wisdom, that rules man's life.

Men ought to be most annoyed by the sufferings which come from their own faults.

A man does not wonder at what he sees frequently, even though he be ignorant of the reason. If anything happens which he has not seen before, he calls it a prodigy.
