使用“lies in”这一短语表示“在于”，准确表达了力量与韧性之间的归属关系，结构清晰严谨。
What you did three years ago or yesterday no longer matters; what counts is what you are doing today. It is better to suffer early in life than late. Life is exhausting—if you do not feel tired now, you will feel even more exhausted in the future. Life is bitter—if you do not taste bitterness now, it will become even more bitter later. All things are interconnected and counterbalanced; without the low, there is no high; without bitterness, there is no sweetness. Only after enduring hardship can one appreciate leisure, and only after experiencing pain can one truly understand joy.
While you are young, step out boldly to face the trials of wind, frost, rain, and snow. Cultivate a heart that is patient, open-minded, and wise. You must save yourself; only then will happiness arrive, for no one else can truly help you. An egg broken from outside is food, but broken from inside is life. Life is the same: pressure from outside is stress, but breaking from within is growth.
If you wait for others to break you from the outside, you are destined to become their prey. But if you break through yourself from within, you will find that this growth is equivalent to rebirth.
There is no job that is not hard, and no interpersonal relationship that is not complex. Starting today, smile every day. Aside from life and death, everything else is trivial. No matter what troubles you encounter, do not torment yourself. No matter how bad things get today, do not feel sad. Today is the youngest day you will ever be in the future; because there is a tomorrow, today is merely the starting line. After putting in the effort, you will realize that many difficulties can be overcome through persistence. In the end, a person’s strength lies in their resilience.
过去的经历已不重要，关键在于当下的行动。人生若晚吃苦，不如早吃苦；当下的轻松往往预示着未来的沉重，当下的安逸可能意味着日后的艰辛。万物相生相克，无下则无上，无低则无高，无苦则无甜。唯有经历过劳累，才能懂得闲暇的可贵；唯有品尝过苦楚，才能感知甜蜜的滋味。
趁着年轻，应大胆走出去，接受风霜雨雪的洗礼，练就一颗忍耐、豁达且睿智的心。唯有自救，幸福才会降临，因为除了自己，没有谁能真正帮你。鸡蛋从外打破是食物，从内打破则是生命；人生亦然，从外打破是压力，从内打破则是成长。
若等待他人从外部打破你，你注定成为他人的牺牲品；若能让自己从内部突破，你将发现这种成长等同于一次重生。
世间没有不辛苦的工作，也没有不复杂的人事关系。从今天起，请保持微笑。除了生死，其余皆为小事。无论遇到何种烦心事，都不要为难自己；无论今天发生多么糟糕的事，都不必感到悲伤。因为今天是未来日子里最年轻的一天，有明天在，今天永远只是起跑线。努力过后你会发现，许多事情只要坚持，终会过去。一个人的本质，拼的就是坚强。
