Almost all the leaves have been stripped from the trees, but there are still a few hanging on and keeping their view of the world before them.
Exerting effort to avoid being trampled underfoot. But those leaves still on the tree are so dried out, sunwashed, and brittle that when they finally rest upon the ground, instead of carpeting a path, they will be crumbled into dust.
Matthew 9: 12 & 13
"But when Jesus heard that, he said unto them, They that be whole need not a physician, but they are sick. But go ye and learn what that meaneth, I will have mercy, and not sacrifice: for I am not come to call the riteous, but sinners to repentance."
