Perfection is simply a fleeting ideal. It is impossible (physically, phychologically etc.) to create something free of errors since mankind is inherently flawed and also because perfection is subject to a person's personal opinion. The "perfect" vacation for someone else for example would be Hawaii or the Bahamas... That isn't so for me, I would choose some place more "off the beaten track" and in a cooler climate.
I think my novel in progress would be pretty good for a story, perhaps one day it will sell a billion e-copies.
