Letters 4.5

Rehearse this thought every day, that you may be able to depart from life contentedly; for many men clutch and cling to life, even as those who are carried down a rushing stream clutch and cling to briars and sharp rocks.

Most men ebb and flow in wretchedness between the fear of death and the hardships of life; they are unwilling to live, and yet they do not know how to die.

Seneca, Letters to Lucilius 4.5, translated by Richard Mott Gummere
