This is so important for new writers to remember. If you obsess over making it perfect, it will fail. It will never be perfect. If you create a new standard of what perfect is, perhaps a standard you know you can attain, then yes, you can make perfect happen. However, my experience reading submissions when I was editing an anthology showed me that even pieces which some might consider unperfect — those that broke standards or experimented, mean they were perfect for me as an editor. Editors have subjective tastes, just like everyone else.
