Section 3: Great Minds Cannot Give Back Wasted Years explained simply

III. Were all the brightest intellects of all time to employ themselves on this one subject, they never could sufficiently express their wonder at this blindness of men’s minds: men will not allow any one to establish himself upon their estates, and upon the most trifling dispute about the measuring of boundaries, they betake themselves to stones and cudgels: yet they allow others to encroach upon their lives, nay, they themselves actually lead others in to take possession of them. You cannot find any one who wants to distribute his money; yet among how many people does every one distribute his life? men covetously guard their property from waste, but when it comes to waste of time, they are most prodigal of that of which it would become them to be sparing. Let us take one of the elders, and say to him, “We perceive that you have arrived at the extreme limits of human life: you are in your hundredth year, or even older. Come now, reckon up your whole life in black and white: tell us how much of your time has been spent upon your creditors, how much on your mistress, how much on your king, how much on your clients, how much in quarrelling with your wife, how much in keeping your slaves in order, how much in running up and down the city on business. Add to this the diseases which we bring upon us with our own hands, and the time which has laid idle without any use having been made of it; you will see that you have not lived as many years as you count. Look back in your memory and see how often you have been consistent in your projects, how many days passed as you intended them to do when you were at your own disposal, how often you did not change colour and your spirit did not quail, how much work you have done in so long a time, how many people have without your knowledge stolen parts of your life from you, how much you have lost, how large a part has been taken up by useless grief, foolish gladness, greedy desire, or polite conversation; how little of yourself is left to you: you will then perceive that you will die prematurely.” What, then, is the reason of this? It is that people live as though they would live for ever: you never remember your human frailty; you never notice how much of your time has already gone by: you spend it as though you had an abundant and overflowing store of it, though all the while that day which you devote to some man or to some thing is perhaps your last. You fear everything, like mortals as you are, and yet you desire everything as if you were immortals. You will hear many men say, “After my fiftieth year I will give myself up to leisure: my sixtieth shall be my last year of public office”: and what guarantee have you that your life will last any longer? who will let all this go on just as you have arranged it? are you not ashamed to reserve only the leavings of your life for yourself, and appoint for the enjoyment of your own right mind only that time which you cannot devote to any business? How late it is to begin life just when we have to be leaving it! What a foolish forgetfulness of our mortality, to put off wholesome counsels until our fiftieth or sixtieth year, and to choose that our lives shall begin at a point which few of us ever reach.
