The lie of "later I'll really live"

There's a sentence almost everyone says some version of. After this promotion. Once the kids are grown. When I pay off the truck. After I retire — then I'll really live. The number changes; the move is the same. You file the real living under a future date and grind through the present like a down payment on it.

Seneca heard it two thousand years ago, word for word. "You will hear many men say, 'After my fiftieth year I will give myself up to leisure: my sixtieth shall be my last year of public office'" (Of the Shortness of Life III, Stewart). Then he asks the question that pops the whole thing: what guarantee do you have that your life will last that long? Who promised you the fiftieth year?

The dock worker counting down to a pension, the cook saving for the place of her own, the parent who'll rest "once things settle": nobody guaranteed any of them the arrival. And even if it comes, a life spent only reaching the finish line never learned how to live the days. You don't switch living on at sixty. You practice it now or you never do.
