Every creator painfully experiences the chasm between his inner vision and its ultimate expression.
– Isaac Bashevis Singer
Do you suppose that’s why Monet painted so many pictures of his flower garden — he was trying to capture it on canvas exactly as he was seeing it?

I don’t believe a writer is ever fully satisfied that he has communicated exactly what he wanted to say, in exactly the way he wanted it to come out.
God the Creator is also painfully aware of the chasm between the world as He wanted it to be and the world as it really is. But in this case it is not the fault of the Creator. After all, He started with paradise, the Garden of Eden. We, the creatures, messed that up; and we continue to mess up the world, because we think we have a better idea.
