Consider how much more you often suffer from your anger and grief, than from those very things for which you are angry and grieved.
Mark how fleeting and paltry is the estate of man--yesterday in embryo, tomorrow a mummy or ashes. So for the hairsbreadth of time assigned to thee, live rationally, and part with life cheerfully, as drops the ripe olive, extolling the season that bore it and the tree that matured it.
Opinion is the main thing which does harm or good in the world. It is our false opinions that ruin us.
