If you work rotating shifts, you think about time differently from most people. You know exactly how many days are left in the set. You count hours to the next relief. You know what 3 a.m. feels like on the fourth night in a row. Time is the thing the job buys from you.
About two thousand years ago a Roman named Seneca wrote a short essay about time. It is called On the Shortness of Life, and it is still in print, because the problem he described never went away.
Who Seneca was
Lucius Annaeus Seneca was a Stoic philosopher, a playwright, a very rich man and, for years, an adviser to the emperor Nero. He knew busy. He also knew how quickly things can be taken away: he was exiled once, and late in life Nero ordered his death, in the year 65.
He wrote On the Shortness of Life as a short treatise addressed to Paulinus, a high official in charge of Rome's grain supply. Paulinus was one of the busiest men in the empire. Seneca's message to him was, roughly: you are giving your life away, and you don't even notice.
Life is not short, we make it short
Seneca opens with a complaint everyone has heard: life is too short. He disagrees. Life is long enough, he says, if we use it well. The trouble is that we waste so much of it.
He makes a sharp observation about how people treat money and time. Nobody lets a stranger walk off with their money. People guard their property, fight over a fence line, argue over a bill. But they let anyone take their time. They give hours away to things they don't care about, to people they don't like, to worry about things that never happen, without a second thought. Time is the one thing you can never earn back, and it is the thing people spend most carelessly.
The trap of "later"
The habit Seneca attacked hardest was postponement. People say they will live properly later: after this project, after retirement, after the kids are grown. Meanwhile, the life they have today goes by unused.
He thought this was the biggest waste of all, because it gives away the only time you actually have. Tomorrow isn't promised. The present is. Putting off living, he said, loses today while you wait for a future that may not come.
For a shift worker, this has a special edge. It is easy to treat days off as recovery only, and to say the real living will start when the schedule changes, when the overtime slows down, when you retire. Seneca would say: that may be a long time. What are you doing with this week?
Claim yourself
In his letters to another friend, Lucilius, Seneca put it in three Latin words: vindica te tibi. Roughly, "claim yourself for yourself." Take back ownership of your own time.
He gave practical advice. Notice where your time goes, the way you would track money. Some of it is taken from you; some slips away; some you simply waste. Once you see it, you can start taking some of it back.
What Seneca did not mean
Seneca was not telling people to quit their jobs. He worked hard his whole life and wrote a huge amount. Work was not his enemy. Busyness without purpose was. A shift spent doing careful, honest work is not wasted time. An evening spent scrolling on a phone because you're too tired to choose something better might be.
He also didn't mean you should fill every hour with self-improvement. One of the things he thought was worth time was simply being with friends and thinking, unhurried.
A practice for the rotation
Here is a way to use Seneca on a rotating schedule.
- Count it. Look at your next set of days off. Write down roughly how the hours went last time. Sleep, chores, errands, screens, people. Just notice.
- Choose one block. Pick one block of time on the next set of days off that you will spend on purpose: with someone you love, on something you have been putting off "until later," or on rest that actually restores you.
- Say no once. Turn down one thing that takes time and gives nothing back.
- Don't wait for the schedule to change. Live on the schedule you have.
The point
Seneca's question is simple, and a little uncomfortable: if someone asked you to account for your time the way an auditor accounts for money, what would the books show?
You can't add hours to a day. But you can stop giving so many of them away. That, Seneca thought, is how a life becomes long enough.
