以After引导的时间状语开头，后接情态动词must not表示强烈的禁止和建议，逻辑清晰。
If you hesitate before victory, you will often only embrace defeat; if you persist through difficulties, you will often achieve new success.
Light and shadow play upon our fingertips. The autumn river carries away not only the mud and sand, but also the innocence of our youth. It seems like just yesterday we were sneaking into each other's dorm rooms, sharing friendly jokes. Now, we have gone our separate ways—some for a simple life, some for a persistent spiritual pursuit, and some merely chasing the fragmented dreams of childhood.
Through the years, whether one is happy or not depends on one's heart. Life is a series of ups and downs. From childhood to adulthood, from adulthood to establishing a family, and from a family to one filled with descendants, this journey is full of obstacles. When you look back in old age at your past dreams, you will always smile as you recall the past. Even if the memories are blurry, even if they are fragmented and broken, you will smile at your own bravery in youth.
If you must choose the path that suits you from among the tens of thousands available, you should strive to act within your capabilities based on your unique strengths and interests. Determine your goals according to your current environment, conditions, and innate qualities.
Do not conclude that you are incompetent because of a small mistake. Always remember that "No one is perfect; who can be without fault?" Once you know you are wrong, you must correct it. After correcting it, you must not repeat the mistake. Then, the path will still be walkable.
如果在胜利前却步，往往只会拥抱失败；在困难时坚持，常常会获得新的成功。
光影游离于指尖，一江秋水带走的不只是泥沙，还有少年的稚嫩，仿佛昨日他们还互蹿着寝室，开着友好的玩笑，而今各自东奔西走，或为简单的生活，或为执着的精神追求，或只为那儿时残梦。
历经岁月里，幸福与否、在于心而已。起起伏伏便是一生，幼儿到成年，成年到成家，成家到子孙满堂，这一路，走的在坎坷，当你老年旧梦时，总会微笑的回忆起曾经，哪怕是模糊不堪，支淋破碎，也会笑自己年轻时的勇敢。
如果要在这上万条道路中选择好适合自己的道路，那么我们就应该努力根据自己的特长，兴趣爱好来量力而行。根据自己所处的环境，条件和自己的本能素质来确定自己的目标。
别因为一点小小的出错，而认定自己无能，牢记"人非圣贤，熟能无过？"知道错了，就要去改，改了就不能再犯，那么路还是能再走下去。
