Do not be wise in words - be wise in deeds.

Whoever values peace of mind and the health of the soul will live the best of all possible lives.

From Apollonius I learned freedom of will and undeviating steadiness of purpose; and to look to nothing else, not even for a moment, except to reason.

Do every act of your life as if it were your last.

Everything that happens happens as it should, and if you observe carefully, you will find this to be so.

The act of dying is one of the acts of life.

Look at everything that exists, and observe that it is already in dissolution and in change, and as it were putrefaction or dispersion, or that everything is so constituted by nature as to die.
