Cleaner's revelation

Everyone must know the cleaners! They all contribute to their city in obscurity.
I wake up every morning and can see a cleaner grandfather sweeping the floor. He looks almost 70 years old, has a lot of wrinkles on his face, looks very tired, very hard, maybe so many wrinkles are because the cleaners are too hard to have it! Every morning, he may get up at 5:6! After getting out of bed, I might have rushed to sweep the floor, and didn't even eat breakfast! Maybe I haven't rested yet! Maybe he. . . . . .
Seeing him every morning, he seems to be in good spirits, not to say that he is very tired, not resting well. He did not say anything, but worked hard in obscurity and used his actions to describe the spirit of the cleaner.
He, obscured, he, hard work, he, selfless dedication, he, do not say a word, he. . . . . .
Cleaners are an indispensable part of the world, because with them, our cities can become cleaner and better.
“Do everything like a cleaner, doing everything you can to do your job.”
This is the revelation brought to me by the cleaners.
