Perfection is a destination for some, and it's there, just over the horizon. You can't see it, but if you keep going you'll always be moving towards it—forever.
As I say, perfection is a fool's errand, but I also have a grave dislike of the term, "good enough." I understand how many use it, but what is it? I could publish a first draft and say, "It's good enough."
I suppose my preference would be that I publish when a work "meets my standards," which are high, but not perfection.
