The Foolish Old Man Removes the Mountains
太行、王屋二山，方七百里，高万仞，本在冀州之南，河阳之北。北山愚公者，年且九十，面山而居。惩山北之塞，出入之迂也，聚室而谋曰：吾与汝毕力平险，指通豫南，达于汉阴，可乎？杂然相许。
There were two mountains, Taihang and Wangwu, seven hundred li wide and ten thousand zhang high. They stood in the north of Jizhou and south of Heyang. An old man named Yugong, nearly ninety years old, lived facing the mountains. Frustrated by the blocking of the north and the tortuous path, he gathered his family and said, Let us work together to level these mountains. If we do this, we can open a road to the south of Yu.
只要有恒心和毅力，就没有克服不了的困难。
As long as there is perseverance and determination, there is no difficulty that cannot be overcome.
After the moral, ask one question: if a similar choice showed up today, where does the story snag? Name that tension first—then take your own step. You need not copy the ancients, only borrow their clarity.
