Spilt water cannot be recovered, and a boat, once built, cannot be unmade. Once something has happened, no one can reverse it. The key lies in whether we choose to learn from it or remain trapped by it; this depends entirely on our own attitude.
Slowly, everything fades; gradually, everything is forgotten. It is often so with the things of this world: without care, familiar relationships fade away; without reflection, familiar stories are gradually forgotten. The wind of time can not only blow away the emotions in our hearts but also cool our feelings; the hand of time can not only blur the image in our eyes but also erase the memory in our minds. Some people are destined to become the past, and some paths are destined to be walked alone. Some people, some things, must eventually be let go.
Let go of the hand, ask nothing, and treat it as the last indulgence for this affection.
People should be persistent, but never obsessive. There are many things in this world that cannot be changed. We should learn to change everything we can change and adapt to everything we cannot. Changing the world is difficult, but changing oneself is relatively easier. What is not meant for us is of no use, no matter how much we like it. Do not pay excessive attention to certain people or things. Let nature take its course and face life with the best possible mindset.
覆水难收，木已成舟。事情既然已经发生，任何人都无法逆转。关键在于我们是选择从中汲取教训，还是任由其困扰，这完全取决于我们自己的态度。
慢慢地，一切都淡了；渐渐地，一切都忘了。世间事往往如此：如果不加呵护，熟悉的人情会慢慢变淡；如果不曾回味，熟悉的故事会渐渐遗忘。岁月的风，不仅能吹淡心中的情感，也能冷却彼此的心；时光的手，不仅能模糊眼中的形象，也能淡忘心中的记忆。有些人注定成为故人，有些路注定要独自前行。一些人与一些事，终归要放下。
松开手，不问一句，当作最后一次对这份感情的溺爱。
人应当执着，但绝不可偏执。世界上有许多事情是无法改变的，我们应该学会改变一切所能改变的，适应一切无法改变的。改变世界很难，改变自己却相对容易。不属于我们的，再喜欢也无济于事。不要过分在意某些人和事，顺其自然，以最佳的心态面对生活。

"The environment will not change for anyone; the real solution lies in changing yourself."
"To change things, one must first change oneself"
