If you think good work is somehow synonymous with perfect work, you are headed for big trouble. Art is human; error is human; ergo, art is error. Inevitably, your work (like, uh, the preceding syllogism…) will be flawed. Why? Because you're a human being, and only human beings, warts and all, make art. Without warts it is not clear what you would be, but clearly you wouldn't be one of us.
