Origin Story
从前，有个年轻的木匠，他技艺精湛，却总是因为轻敌而导致作品瑕疵百出。一次，他接了个大活，要雕刻一个精美的花瓶。他过于自信，没有仔细规划，结果花瓶在雕刻过程中裂开了。这次失败让他痛定思痛，他开始认真研究雕刻技艺，仔细规划每一个步骤，反复练习。之后，他雕刻的花瓶越来越精细，名声也越来越响亮。从此，他明白了吃一堑，长一智的道理，再也没有因为轻敌而失败过。
Once upon a time, there was a young carpenter who was skilled in his craft but often made mistakes due to overconfidence. He once took on a large project, carving a beautiful vase. Overconfident, he didn't plan carefully, and the vase cracked during the carving. This failure made him reflect deeply. He began to seriously study the art of carving, carefully planning each step, and practicing repeatedly. Afterward, the vases he carved became increasingly refined, and his reputation grew. From then on, he understood the meaning of 'learning from mistakes' and never failed again due to overconfidence.
