Join your short span to all of it

Here's the trap in the view from above: see your career as one small figure among the herds, and it can start to feel pointless. One short span, a few decades of shifts, then forgotten. Why bother doing any of it well? Seneca, who could make a working life feel small, also gave the way out — and it's the whole point of the week.

The wise, he wrote, "do not merely enjoy their own lifetime, but they annex every century to their own: all the years which have passed before them belong to them" (Of the Shortness of Life XIV, Stewart). You are not stuck inside your forty years. Every craftsman who solved the problem before you, every nurse who wrote down what worked, every parent who passed down a way of doing things — their time is available to yours. Take it. And the work you do well outlives your span the same way, handed to whoever comes next.

That's the keystone. A short arc, lived wisely, stops being short. The line cook who learns the old recipes and teaches the new kid is no longer living one career — she's living a chain of them. You join your small span to all of it by the way you work.
