On the Shortness of Life

Select passages from Roman philosopher Seneca’s life-changing 2,000-year-old treatise.

We’re huge fans of Seneca’s “On the Shortness of Life,” a 2,000 year old treatise on how we spend and think about our time. Some things truly never change.

We’ve included select passages below, and highlighted some of our favorite ideas. If you’re digging it, we suggest buying the book. Enjoy.

It is not that we have a short time to live, but that we waste a lot of it. Life is long enough, and a sufficiently generous amount has been given to us for the highest achievements if it were all well invested. But when it is wasted in heedless luxury and spent on no good activity, we are forced at last by death’s final constraint to realize that it has passed away before we knew it was passing. So it is: we are not given a short life but we make it short, and we are not ill-supplied but wasteful of it … Life is long if you know how to use it.”

People are frugal in guarding their personal property; but as soon as it comes to squandering time they are most wasteful of the one thing in which it is right to be stingy.”

You are living as if destined to live for ever; your own frailty never occurs to you; you don’t notice how much time has already passed, but squander it as though you had a full and overflowing supply — though all the while that very day which you are devoting to somebody or something may be your last. You act like mortals in all that you fear, and like immortals in all that you desire … How late it is to begin really to live just when life must end! How stupid to forget our mortality, and put off sensible plans to our fiftieth and sixtieth years, aiming to begin life from a point at which few have arrived!”

No activity can be successfully pursued by an individual who is preoccupied … since the mind when distracted absorbs nothing deeply, but rejects everything which is, so to speak, crammed into it. Living is the least important activity of the preoccupied man; yet there is nothing which is harder to learn … Learning how to live takes a whole life, and, which may surprise you more, it takes a whole life to learn how to die.”

Everyone hustles his life along, and is troubled by a longing for the future and weariness of the present. But the man who … organizes every day as though it were his last, neither longs for nor fears the next day … Nothing can be taken from this life, and you can only add to it as if giving to a man who is already full and satisfied food which he does not want but can hold. So you must not think a man has lived long because he has white hair and wrinkles: he has not lived long, just existed long. For suppose you should think that a man had had a long voyage who had been caught in a raging storm as he left harbor, and carried hither and thither and driven round and round in a circle by the rage of opposing winds? He did not have a long voyage, just a long tossing about.”

Indeed the state of all who are preoccupied is wretched, but the most wretched are those who are toiling not even at their own preoccupations, but must regulate their sleep by another’s, and their walk by another’s pace, and obey orders in those freest of all things, loving and hating. If such people want to know how short their lives are, let them reflect how small a portion is their own.”

I am always surprised to see some people demanding the time of others and meeting a most obliging response. Both sides have in view the reason for which the time is asked and neither regards the time itself — as if nothing there is being asked for and nothing given. They are trifling with life’s most precious commodity, being deceived because it is an intangible thing, not open to inspection and therefore reckoned very cheap — in fact, almost without any value. Nobody works out the value of time: men use it lavishly as if it cost nothing … We have to be more careful in preserving what will cease at an unknown point.

No one will bring back the years; no one will restore you to yourself. Life will follow the path it began to take, and will neither reverse nor check its course. It will cause no commotion to remind you of its swiftness, but glide on quietly. It will not lengthen itself for a king’s command or a people’s favor. As it started out on its first day, so it will run on, nowhere pausing or turning aside. What will be the outcome? You have been preoccupied while life hastens on. Meanwhile death will arrive, and you have no choice in making yourself available for that.”

Putting things off is the biggest waste of life: it snatches away each day as it comes, and denies us the present by promising the future. The greatest obstacle to living is expectancy, which hangs upon tomorrow and loses today. You are arranging what lies in Fortune’s control, and abandoning what lies in yours. What are you looking at? To what goal are you straining? The whole future lies in uncertainty: live immediately.”

You must match time’s swiftness with your speed in using it, and you must drink quickly as though from a rapid stream that will not always flow … Just as travelers are beguiled by conversation or reading or some profound meditation, and find they have arrived at their destination before they knew they were approaching it; so it is with this unceasing and extremely fast-moving journey of life, which waking or sleeping we make at the same pace — the preoccupied become aware of it only when it is over.”

If you enjoyed, we suggest buying the book. You can read it in one sitting at the park.
