"putting your art, writing, expression out to be judged by others is an act of bravery as much as talent, and a lot of people lack braver-y. Sorry to say it but if you need your work to be polished and beyond reproach, that's a determination and character problem, not a skill problem."

Or maybe you know enough people are just generally mean and jerk enough that you don't want to listen to their silly criticism and over-the-topness. And there really isn't any benefit to you for putting it out there.
