The Roman philosopher Seneca saw the flaw in human nature long before the internet, before the printing press, before industrialization or any of the technical advancements we believe are chewing up our time:
“No person would give up even an inch of their estate, and the slightest dispute with a neighbor can mean hell to pay; yet we easily let others encroach on our lives — worse, we often pave the way for those who will take it over. No person hands out their money to passersby, but to how many do each of us hand out our lives! We’re tight-fisted with property and money, yet think too little of wasting time, the one thing about which we should all be the toughest misers.”
He is pointing at an asymmetry that should embarrass all of us. We negotiate hard over a few thousand dollars. We will litigate over a fence line. And then we hand over an entire afternoon to a meeting that should have been an email, or worse: we will override our screen time limits on Instagram and burn an hour doomscrolling.
As Seneca says, we pave the way. We volunteer. We hand over massive amounts of time to enrich the media companies we did not owe, on a day we could not spare even a minute and somehow managed to slip behind on important promises we’ve made, didn’t get to the gym and skimped on precious family time.
Time Is the Only Portfolio That Cannot Grow
Every other asset we own can compound. Cash earns interest. Equity appreciates. Relationships deepen. Skills stack. Put money in and it can come back bigger.
Time only goes one direction: down. There is no deposit. There is no bull market. There is no strategy that adds a single hour to the balance.
Every moment is a use-it-or-lose-it opportunity, which means the only real question we ever get to answer is allocation. Not how much time we have. What we spend it on.
The Big Rocks
There is an old story that makes this concrete better than any spreadsheet.
A professor stood before a class with a large empty jar. First he filled it with big rocks, until it appeared full. Then he poured in gravel, which settled into the gaps. Next came sand. Finally, he poured in water.
He asked the students, “What is the lesson?”
One student said, “No matter how full our life is, we can always fit more in.”
The professor said, “That is not the lesson. The lesson is this: if you do not put the big rocks in first, you will never get them in at all.”
That is the whole thing. Work, errands, media, friends, hobbies, the group chat, the inbox — these are the gravel, the sand, and the water. They are not bad. They are just infinitely compressible. They will fill every available space, and they will fill it perfectly, and at the end of the week the jar will look completely full.
But if the big rocks did not go in first, they never went in at all.
What Sits at the Apex
At the apex of our lifestyle is whatever we decide to prioritize above everything else. It sits at the top of the list every single day, and everything else gets built around it. Family, work, fitness, faith, fun — the answer is personal, and it changes across a life. What matters is that there is an answer, and that we actually know what it is.
Most people have never named theirs. They have preferences, and they have guilt, and they have a vague sense that they should be spending more time on something. That is not an apex priority. That is a wish.
An apex priority is a decision that other things lose to. If nothing ever loses to it, it is not at the apex. It is just something we like.
Protect It Like a Fortress
Naming the apex is the easy part. Defending it is the work.
The Question
So the questions are simple, even if the answers are not.
What is our mission? What is genuinely most important? And are we willing to commit to it and let everything else flow around it, into whatever space is left?
The gravel, the sand and the water will always find their way in. They do not need our help.
Put the big rocks in first.
