Remember how often you have postponed minding your interest, and let slip those opportunities the gods have given you. It is now high time to consider what sort of world you are part of, and from what kind of governor of it you are descended; that you have a set period assigned you to act in, and unless you improve it to brighten and compose your thoughts, it will quickly run off with you, and be lost beyond recovery.

All that is from the gods is full of Providence.

While you live, while it is in your power, be good.

Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are, and to make new things like them.

This is enough. Do not add, And why were such things made in the world?

...the infallible man does not exist.

Give full attention and devotion to each act.
