I see that you have come to the last stage of human life; you are close upon your hundreth year, or even beyond: come now, hold an audit of your life. Reckon how much of your time has been taken up by a money-lender, how much by a mistress, a patron, a client, quarreling with your wife, punishing your slaves, dashing about the city on your social obligations. Consider also the diseases which we have brought on ourselves, and the time too which has been unused. You will find that you have fewer years than you reckon. Call to mind when you ever had a fixed purpose; how few days have passed as you had planned; when you were ever at your own disposal; when your face wore its natural expression; when your mind was undisturbed; what work you have achieved in such a long life; how many have plundered your life when you were unaware of your losses; how much you have lost through groundless sorrow, foolish joy, greedy desire, the seductions of society; how little of your own was left to you. You will realize that you are dying prematurely.
Seneca, On the Shortness of Life
