I have an old ex-girlfriend who told me a story about a creative writing class she took. In the classroom was a sign. Often students would read their work out loud, but before they did, they would almost always take a second first to silently point a finger at the sign.
The sign said something like this:
"If you think you're writing is rough, too short, too long, cheesy, choppy, unfinished, something you're still working on, just something you did last minute, weird, etc, do not say so, just point to this sign."
It saved everyone a lot of time and trouble, and let people get on with the real process of sharing and improving their technique as writers and artists.
