In today's society, time holds a significant position in every individual's life. Once time has passed, it never returns, much like spilled water that cannot be recovered. Hence, the ancients coined the saying 'Time is gold'. Time brings us joy, sorrow, and valuable life lessons. So what is time? Why is it said that time is gold? Time is the designated periods in a day, month, year, etc. With time, we can accomplish many tasks in life; time is the essential condition for creating the colorful life we desire. For each person, time is life, wealth, knowledge, etc. In general, time is invaluable, cannot be bought with money, and it continues to pass indifferently in this increasingly progressive society. Human beings can invent great achievements in a short period. Yet, there are people who do not value time, allowing it to pass while doing futile things. Truly, time is extremely precious, more valuable than gold. But what matters is what we do rightly and beneficially for everyone, society, with the time we have. Therefore, we should understand the value of time, utilize every second and minute to do useful things, so that we will never regret or lament wasting time controlling us.

Time is linear, constantly moving and evolving without pause. Time waits for no one, so cherish every second, every minute you have. And don't forget to share your time with others to turn your time into your happiest moments! If we talk about what in nature is both worthy of respect and fear, then perhaps it is time. Time is truly important; it is also the treasure of humanity. Time is simultaneously the most frightening thing; it can turn a boy into an old man and a sapling into a pile of firewood. Time also helps us grow, mature, to work and do all the necessary and important things in life. However, what makes the position, the role of time special here is its irreversible nature. Indeed, time is like words spoken, cannot be taken back; time is like arrows shot, cannot be drawn back. We can see that every second, every minute, every hour of time seems to have many changes, flowing away, creating a past that can never be regained. Time is truly precious if we know how to value it and manage it in the most organized and scientific way possible. And time will be meaningless when it is in the hands of those who do not know how to use it and cannot plan their own time.

I once read a poem by Văn Cao:
Time passing through fingersDries up the leavesMemories in meFall like pebbles into a dry well.Only the green verses remainOnly the green songs remainAnd your eyes are like two wells of water.
Indeed, it is so. Time seems to have mass; we can weigh, measure, and feel its presence. Time passes very quickly; in the blink of an eye, the day has dawned, has turned to night, in the blink of an eye, we have grown into adults. Time passes smoothly, silently, without waiting for anyone, yet it has a terrifying destructive power over everything around us. No matter how solidly constructed the architectural works are, they are eventually decayed by time; the dreams, aspirations that we nurture are also extinguished. However, the spiritual values, the vitality of intense love, defy all odds, surpassing all obstacles of space and time to exist eternally. Even just a song, a poem, can be preserved for thousands of years for future generations to know. From fairy tales like Tấm Cám, Thanh Sanh,... to glorious historical events like the Trưng Sisters riding elephants to fight invaders or President Hồ Chí Minh seeking ways to save the country, though they happened long ago, people still remember them. Therefore, each of us needs to cherish those moments, sacred minutes, precious, preserving the beautiful memories in our hearts so that they are etched and exist forever.

Time is the invaluable resource of the entire universe. It's a highly abstract concept that's difficult to explain thoroughly. Time changes everything day by day. Looking at the reality of life, humans are born, grow up, mature, grow old, and then disappear. The same goes for trees or animal species, and even societies change and evolve incessantly. That's the cycle of time that no one can stop. Therefore, humans need to cherish their limited time, make life meaningful, and contribute many good values to the community. However, most of us have not truly been able to do this. The development and proliferation of various social media platforms, new forms of entertainment, distract humans.
