A sheep is gone.
Is it too late
to fix the pen?

The full narration of the video.

One sheep lost outside the pen. Nineteen still inside. The old saying about mending the pen was never about the one that got away. It comes from the state of Chu, over two thousand three hundred years ago. A minister named Zhuang Xin begged King Xiang to stop partying and mind the kingdom.

The king called him a senile old man. So Zhuang Xin left for the state of Zhao. Five months later, the Qin army took the Chu capital. The king fled all the way to Chengyang. He rushed to call Zhuang Xin back, and asked: is it too late?

Zhuang Xin answered with an old saying: spot the hare, then call the hound, and you're not late. Lose a sheep, then mend the pen, and you're not too late. What happened next? The history books say that two years later, the king gathered over a hundred thousand troops and won back fifteen towns along the Yangtze. But the capital never came back to Chu.

The lost one stayed lost. The rest were saved. That's the whole math behind the saying. Let's do the math with a made-up pen. Twenty sheep, one hole in the wall, and every night, one sheep slips out. Mend it the next morning, and nineteen are left. Wait five nights, and only fifteen remain.

Never mend it, and in twenty days the pen is empty. Every day you wait costs one more sheep. So when is the best day to fix it? Always today. And yet some people lose one, and still don't fix the hole.

In the fable told later, a neighbor urged the shepherd to fix the pen. He said: the sheep's already gone, why bother? Next morning, another sheep was missing. We call that thinking: the pot's cracked, so smash it. Psychologists measured it with ice cream. A group of dieters first drank one or two milkshakes, then tasted ice cream, supposedly to rate the flavor.

People who weren't dieting ate almost half as much ice cream after the shakes. That's normal. But the dieters ate over sixty percent more than dieters who'd had no shake at all. The researchers' explanation: they felt the day was already ruined, so they might as well go all out.

That milkshake is the first lost sheep. The real damage comes from the words that follow: might as well. Life works the same way. The lost sheep is what already happened. The hole is what makes it happen again. Mending the pen means blocking that cause. So yes, mending the pen after a loss is still in time. Not in time for that sheep, but for every sheep still inside.

What about you? Lose a sheep, and do you chase it first, or come back and fix the hole?
