I do what is mine to do; the rest doesn't disturb me. (Hays translation) - Marcus Aurelius

As for life, it is a battle and a sojourning in a strange land; but the fame that comes after is oblivion.

An angry countenance is much against nature, and it is oftentimes the proper countenance of them that are at the point of death. But were it so, that all anger and passion were so thoroughly quenched in thee, that it were altogether impossible to kindle it any more, yet herein must not thou rest satisfied, but further endeavour by good consequence of true ratiocination, perfectly to conceive and understand, that all anger and passion is against reason.

Let there be freedom from perturbations with respect to the things which come from the external cause; and let there be justice in the things done by virtue of the internal cause, that is, let there be movement and action terminating in this, in social acts, for this is according to thy nature.
