Once, a weasel challenged a lion to a duel. The lion resolutely refused. "What, are you afraid?" the weasel asked. "Extremely afraid," the lion replied, "for if I agree, you will gain the honor of having fought a lion, while I will be mocked by all animals for fighting a weasel."
There was once a young American writer who, in his early years, produced many popular works that were well-received by readers. One day, he had a dispute with a local petty man over trivial matters, and neither would back down. Friends advised him not to argue with such a person, as his time was precious and should be spent on writing. However, the writer could not let it go; he felt the man had tarnished his reputation and insulted his character, and he was determined to defeat him and win his submission. From then on, he was constantly at odds with this "enemy," caught in endless conflicts. Consequently, he lost his passion for creation and failed to produce any more satisfying works. Years later, many had forgotten he ever existed.
This teaches us a profound truth: the higher the goals a person pursues, the faster their talents develop, and the more they contribute to society.
有一次，一只鼬鼠向狮子发起挑战，试图与狮子决一死战。狮子果断地拒绝了。鼬鼠问道：“怎么，你害怕了吗？”狮子回答说：“我确实非常害怕。如果答应了你，你便能获得曾与狮子比武的殊荣，而我呢？此后所有的动物都会嘲笑我竟然与一只鼬鼠纠缠。”
美国曾有一位年轻作家，早年创作了许多脍炙人口的作品，销量颇佳，深受读者好评。然而有一天，他与当地一位市侩因琐事发生矛盾，双方互不相让。朋友曾劝他不要与市侩计较，因为他的时间极其宝贵，应当专注于写作。但作家却难以释怀，他认为对方破坏了自己的声誉，侮辱了人格，执意要战胜对手并让对方心悦诚服。从此，他与这位“敌人”针锋相对，纠缠于不断的冲突与摩擦中。这导致他再也无法静心创作，作品质量也大不如前。多年以后，人们早已忘记过这样一位作家。
这带给我们一个启示：一个人追求的目标越高，其才干的发展就越快，对社会也越有益，这是一个不言而喻的真理。
"Whatever we do, we should possess the spirit of courage."
"Every first and every challenge demands the support of courage."
"Only with a heart full of hope can one move forward bravely."
"Failure may bring disappointment, but not trying guarantees defeat."
"Those who do not see every detail often move forward more bravely."
