使用了转折连词 but 连接两个对比句，增强了语气的坚定感。
He was born in an obscure small town in South Korea. Growing up in a poor family, his mother, a modest postal worker, had high hopes for him. He also had a younger sister.
However, he was a very unconfident person. During his elementary school years, he never even raised his hand to answer a question in class. Once, during a school swimming competition, he stood by the riverbank, trembling with fear, unable to take a single step forward.
When his mother heard about this, she was furious. Despite being physically weak following a recent surgery, she took her son to the riverbank and pointed at the rushing waters, saying, "Jump in." Terrified, he retreated, pleading, "I don't know how to swim, I'm afraid." His mother patted his shoulder and said patiently, "Child, you must understand that often, we fail because we are bound by our past experiences. I don't know how to swim either, but with courage and perseverance, I will succeed." With that, she took off her shoes and plunged into the water.
His heart raced with intense anxiety. One second, two seconds... five seconds later, the brave mother, after choking on water several times, miraculously surfaced.
"So, my child, what is your dream now?" his mother asked, walking back to him, drenched from head to toe.
他出生在韩国一个默默无闻的小镇，家境清贫，母亲是一名平凡的邮政职工，他还有一个妹妹。由于生活不易，母亲从小就对他寄予了厚望。
然而，他却是个极度缺乏自信的人。上小学时，他甚至不敢在课堂上举手回答问题。有一次，学校组织游泳比赛，他站在河边，因为恐惧而瑟瑟发抖，迟迟不敢向前迈出一步。
母亲得知此事后非常生气。尽管她刚做完手术，身体还很虚弱，她还是带着孩子来到河边，指着奔腾的河水说：“跳下去。”他吓得赶紧向后退缩：“我不会游泳，我怕。”母亲拍着他的肩膀，耐心地劝导道：“孩子，你要明白，很多时候我们之所以无法成功，就是因为被过去的经验所束缚。我同样不会游泳，但凭着勇气和恒心，我一定能成功。”说完，她毅然脱下鞋子，跳进了水中。
他的心瞬间提到了嗓子眼，紧张得狂跳不止。一秒，两秒……五秒钟后，那位勇敢的母亲在呛水几次后，竟然奇迹般地浮了起来。
“那么孩子，你现在的梦想是什么？”母亲浑身湿透地走回岸边，轻声问道。
