One cannot step into the same river twice

One cannot step into the same river twice "One cannot step into the same river twice." This is the ancient Greek philosopher Heraclitus's quote. What he means is that people and rivers are constantly changing. The water, stones, sand, organisms, molecules, atoms, etc. in the river are moving and changing all the time. Therefore, what you step into for the second time has already changed. Not the same river. Even people are not the original people because everything has changed. This river is no longer the other river.

Yes, everything is changing, and many things cannot go back to the past. Instead of feeling empty and sad about the passing river, it is better to cherish the present and seize the present.

Personally speaking, everyone is recognizing and remembering something new every moment. Invisibly, other things are gradually forgotten. People's values ????are constantly and gradually revised, they realize some new ideas, and abandon some wrong and immature concepts. People's character is constantly growing, and slowly with the Go through changes. The memory, personality, and values ??of who I am now are definitely very different from who I was a year ago or ten years ago. So am I still me?

These questions are inseparable from Heraclitus's famous saying, "One cannot step into the same river twice." Imagine a roll of wool stretched one hundred meters long. This wool thread is made up of countless wool threads twisted together, or woven together. No single piece of wool is a hundred meters long. The original length of wool is limited, and soon it reaches the end. New wool is added one after another and continues to extend. This continues, and the length is finally woven into a piece of hair that is one hundred meters long. A strand of wool.

So, even if the fiber at the other end of the wool is completely different from this end, as long as it is not cut from it, we still think it is the same wool.
