I read a stat recently that stuck with me. In a December 2025 YouGov survey of over 2,000 US adults, roughly 40% said they did not read a single book in 2025. The typical American read two. And a small group of heavy readers, the top 19%, accounted for 82% of all books read.

Whatever else that tells us, it says that for a lot of people, active learning quietly probably stopped at some point and never really started again.

I should say up front that I am a curious generalist here, not a psychologist or an economist. This is reading and reflection on some research, not advice, and the studies I mention are findings from particular groups of people, not settled science or universal rules about you.

Which brings me to Seneca. He asked: “What is more foolish than refusing to learn, simply because one has not been learning for a long time?” That line has been rattling around in my head for weeks.

It is as if it was aimed squarely at the excuse tucked inside that 40% figure, the quiet assumption that if you stopped years ago, the door has closed behind you. Seneca’s answer is that the length of the gap is not the point. Refusing to start again because of it is the only foolish part.

Learning is a verb, not a phase you finish

Most of us carry a map that goes: learn hard for two decades, then work, then coast. School first, then done. It is a tidy story, and I think it is mostly wrong.

Seneca was not talking about piling up facts anyway. In On the Shortness of Life he wrote, “It takes the whole of life to learn how to live.” That is not a syllabus. It is the slower, harder business of learning how to live well, which never really closes.

The AI-age case, without the doom

Perhaps the strongest modern argument for lifelong learning comes from the job market, and it is not the fun one. The World Economic Forum’s Future of Jobs Report 2025 found that employers expect 39% of workers’ core skills to change by 2030. The same report names curiosity and lifelong learning among the human skills rising in importance this decade.

I feel this one personally, and not always happily. AI has changed how I work. My old research edge, dual screens and clever search terms, is largely gone, because these tools find sources fast. What they cannot do, at least not yet, is make the judgment calls or reliably find the angle. I still decide how to use a source and what a piece is actually about. So I have come to see AI as a tool to make me better, not a tool to make the job easier, and I suspect quality is where the difference will sit.

There is a generational edge to this too. A lot of the career paths my generation worked toward feel like they are quietly going obsolete without constant new skills. Millennials are caught in an awkward middle: old enough to have built a career one way, young enough to have decades of working life left and no real choice but to adapt. Most days I feel “learning to stay relevant” as pressure and grind. Some days there is a bit of enjoyment in it, because I have always wanted to stay ahead of the curve.

What I have actually started doing

None of that helps unless it becomes something you do, so I have started scheduling learning like anything else on the calendar. Three evenings a week I try to read at least 30 pages after work. There is also a hands-on skill I keep meaning to pick up, woodwork, that I have planned and re-planned and still not started, because I keep failing to find the time.

I lean toward the James Clear view that you fall to the level of your systems, not the height of your goals. A slot on the calendar does the work willpower keeps failing to do, at least for me. I am not some superhuman disciplined person, and the routine slips more than I would like. But a scheduled 30 pages that sometimes becomes ten still beats an open intention that becomes nothing.

The part I keep circling back to is that learning is not a skill you pick up and file away. It is more like a slow, dots-connecting process you keep applying to the actual living. Reading three nights a week is not the point. It is just the thing that keeps me pointed at the process.

And if the gap has been long, Seneca’s point holds: the length of it is no argument at all.

If any of this is landing more as pressure than as interest, if the sense of falling behind is genuinely weighing on you, a good therapist is worth more than any productivity system.
