"I no longer enjoy the life" said the little man.
Sometimes a lot of things lose their value in my eyes.
It becomes meaningless without reason.

If you are not satisfied; you have to change either your life or where you are or your perspective.
"So if you need light, you shouldn't close your eyes.
If you have already closed your eyes, you shouldn't complain about the light."
