Section 8: People Ask For Time Without Valuing It explained simply

VIII. I am filled with wonder when I see some men asking others for their time, and those who are asked for it most willing to give it: both parties consider the object for which the time is given, but neither of them thinks of the time itself, as though in asking for this one asked for nothing, and in giving it one gave nothing: we play with what is the most precious of all things: yet it escapes men’s notice, because it is an incorporeal thing, and because it does not come before our eyes; and therefore it is held very cheap, nay, hardly any value whatever is put upon it. Men set the greatest store upon presents or pensions, and hire out their work, their services, or their care in order to gain them: no one values time: they give it much more freely, as though it cost nothing. Yet you will see these same people clasping the knees of their physician as suppliants when they are sick and in present peril of death, and if threatened with a capital charge willing to give all that they possess in order that they may live: so inconsistent are they. Indeed, if the number of every man’s future years could be laid before him, as we can lay that of his past years, how anxious those who found that they had but few years remaining would be to make the most of them? Yet it is easy to arrange the distribution of a quantity, however small, if we know how much there is: what you ought to husband most carefully is that which may run short you know not when. Yet you have no reason to suppose that they do not know how dear a thing time is: they are wont to say to those whom they especially love that they are ready to give them a part of their own years. They do give them, and know not that they are giving them; but they give them in such a manner that they themselves lose them without the others gaining them. They do not, however, know whence they obtain their supply, and therefore they are able to endure the waste of what is not seen: yet no one will give you back your years, no one will restore them to you again: your life will run its course when once it has begun, and will neither begin again or efface what it has done. It will make no disturbance, it will give you no warning of how fast it flies: it will move silently on: it will not prolong itself at the command of a king, or at the wish of a nation: as it started on its first day, so it will run: it will never turn aside, never delay. What follows, then? Why! you are busy, but life is hurrying on: death will be here some time or other, and you must attend to him, whether you will or no.
