The real power here lies in Browning's reversal of our usual accounting: he's not saying persistence eventually pays off (the obvious moral), but rather that a single genuine moment of breakthrough *retroactively validates* all the stumbling that came before it. That old mathematician working in obscurity for forty years who finally proves her theorem doesn't just get credit for the theorem—the failures become meaningful chapters in her story rather than wasted time. What transforms them is not mere persistence, but actually succeeding at something that matters, which means your years of mistakes weren't practice runs but essential prerequisites you couldn't have skipped.
