The demand for perfection is always a misunderstanding

 “The demand for perfection is always a misunderstanding of the ends of art. Imperfection is in some sort essential to all that we know of life in a mortal body, that is to say of a state of progress and change. Nothing that lives is, or can be, rigidly perfect; part of it is decaying, part nascent. The foxglove blossom-a third part bud, a third past full bloom, -is a type of the life of this world. And in all things that live there are certain irregularities and deficiencies which are not only signs of life but sources of beauty.”

-John Ruskin.
