Overworking ART!

I am not alone in this. I have read and heard many responses to this thought of a full brained artists mind in paintings not finished yet, not fit to be seen yet, should you keep them a secret till the final unveiling... and then the other thought comes too mind. Overworking your art... I think it is a matter of preference, style and technique. If a piece is haunting you and you are unsure in the finished process as an artist's vision is never complete. My suggestion to myself and others is too turn the piece and give it the time it needs to be realized.
