'While We Wait for Life, Life Passes' — Seneca on Releasing 'Someday' and Beginning to Live Now

Time That Passes While We Say 'Once Things Settle Down'

In the first of his Letters to Lucilius, Seneca left a quiet but cutting observation: Dum differtur vita transcurrit — 'While life is being postponed, life is passing by.' When work settles down, when the kids are older, when I've saved a little more. This line sees straight through the way we actually spend our days.

At the heart of the Stoic view of time is the insight that only the present truly exists. The past is gone; the future has not yet arrived. And yet humans treat the most real thing — the present — with the least regard, throwing their lives toward a future that is not yet here. In On the Shortness of Life, Seneca put it plainly: 'It is not that we have a short time to live, but that we waste much of it.' We do not lack time. We spend our time in the posture of waiting.

The structure has not changed today. Harvard researchers Matthew Killingsworth and Daniel Gilbert used a smartphone app to track the mental states of 2,250 people and found that, on average, we spend about 47 percent of our waking hours thinking about something other than what we are doing. Crucially, the further the mind wandered from the present, the lower reported happiness became. Waiting for 'someday' is, structurally, a way of draining happiness from the present.

Why Seneca Wrote About the Shortness of Life

Seneca was a Roman senator born in Cordoba and tutor to the emperor Nero. On the Shortness of Life, written in his fifties, takes the form of a letter to his cousin Paulinus, but in substance it is a warning to Roman society as a whole.

In his time, the Roman elite treated busyness as a mark of status. Social obligations morning to night, legal appearances, endless banquets. And they all said the same thing: 'What I really want to do, I'll start once I retire.' Seneca tore into this. 'When exactly do you intend to live? Old age weakens the body, dims memory. By the time the someday you are waiting for arrives, you yourself may be gone.'

He was writing this, in part, to himself. Holding high office under Nero, he was aware that daily obligations were pulling him further from the philosopher he intended to be. A few years later he was accused of plotting against Nero and ordered to take his own life. Even at the end, he acted as a philosopher. The resolve to reclaim a postponed life carried him through that final moment.

Three Psychological Mechanisms Behind 'Someday'

Seen through modern neuroscience and behavioral science, three deep mechanisms keep us saying 'someday.'

The first is time discounting. The human brain systematically undervalues distant rewards compared to near ones. 'Today's ease' looks more attractive than 'future fulfillment.' The learning or exercise we say we want is a future reward; the video or social feed is an immediate one. The brain keeps voting for the immediate.

The second is the trap of conditional happiness. Stacking prerequisites — 'once this is done,' 'once I have that.' Psychologist Emily Esfahani Smith called this 'the arrival fallacy.' Because humans hedonically adapt, the instant a condition is met, a new one appears. Happiness does not arrive from meeting conditions. It arrives when we let go of conditioning itself.

The third is fear of change. Beginning to live now also means admitting that the way we have spent time was misaligned. That admission stings. So the vague promise of 'someday' becomes a gentler form of self-comfort. But that comfort is bought with the passing of the very life we hoped to live.

Four Seneca-Style Practices for Reclaiming the Present

Seneca was not content with abstractions. Across his letters and On the Shortness of Life, he left concrete practices.

First, a time audit. At the end of the day, log how you spent your hours in thirty-minute blocks. Most people are startled to find that the time spent on 'what I actually wanted to do' is near zero, while the time simply 'gone' dominates. Seneca wrote, 'People are careful with money but strangely generous with time — the very thing most precious.' Making it visible is the first step.

Second, the ten-minute rule. Start what you keep postponing today, for ten minutes only. Ten minutes is within anyone's reach. What matters is not perfection but the fact that an act once pushed into the future has returned to today. Ten minutes of walking. Ten minutes of reading. Ten minutes on the phone with someone you meant to call. These ten minutes break the chain of postponement.

Third, the 'last day' test. In Letter 61, Seneca advises: 'Live each day as if it were your last.' This does not need to be interpreted dramatically. Simply pause in the morning and ask, 'If today were my last day, would the priorities I am about to follow still be the same?' The answer is very often no. That no is enough to reset the rudder of the day.

Fourth, unconditional joy. Seneca insisted again and again that 'happiness means stepping out of the chain of conditions.' The fact that you woke this morning. The cup of something warm in your hand. Someone you can speak to. These do not wait on future achievement; they are already present. Noting three such unconditional joys a day pulls the axis of happiness from the future back into now.

A Small Moment of My Own — Late at Night in the Kitchen

The other night, after putting the kids to bed, I was washing dishes in the kitchen when a thought came unbidden: 'How many more years will I hear this sound?' The soft clatter of plates, the low hum of the extractor fan, the faint breathing of family in the next room. It was not a special night — just one of thousands of repetitions I had never really paid attention to.

What I realized was that I had been treating those ten minutes in the kitchen as 'a task to get through as quickly as possible,' so that I could start reading, or watching something afterward. But if, years from now, I would look back and realize that those ten minutes were what my life was actually made of, was it really all right to treat this moment as something to get over with? Seneca's 'life passing while we wait for it' is probably not about dramatic scenes. It is about precisely these ten minutes in a late-night kitchen. Since that night, my hands have moved a little more slowly at the sink.

Balancing 'Preparing for the Future' and 'Living Now'

Seneca is not denying the value of planning. He himself wrote a vast body of work for later generations. The issue is the ratio between preparation and living. If preparation keeps swelling and life keeps getting shoved behind it, it is no longer preparation; it is an excuse for delay.

In Stoic terms, 'sacrificing the present entirely for the future' is an act against nature. The future is not guaranteed; only the present is real. The wise way is to prepare reasonably for the future while tasting the very process of preparation as part of living now. If you save, savor today's act of saving as a choice that is yours. If you raise a child, treat the moment not as a waiting room for some finished future but as something already complete.

In Letter 101, Seneca closes: 'To the wise, a day fully lived is richer than an unfinished long life.' Not length, but whether you actually met the present within it, decides a life's density.

Reclaim One Postponement Today

When you finish reading this piece, I'd like you to try one thing. Among the items you keep calling 'someday,' pick the smallest version you could do in ten minutes today. The first page of a book you've been meaning to read. A short message to someone you've been meaning to reach. A stretch that has been on pause for too long. Any of them.

What matters is that you reclaim ten minutes of it today. It doesn't need to be perfect. It doesn't need to continue. Just break, once, the chain of 'someday.' That single break is the first step in taking back, from the 'passing life' Seneca warned about two thousand years ago, the life of this present moment.

Seneca wrote: 'Begin — and already you are alive.' Life does not begin in the waiting room. It begins the moment you stand up from it.
