Lynn Krawczyk asked this question on her blog this morning and my response was:
We can remain stuck and live with continual disappointment or we can move forward declare it done and create more works of art.
"Perfection is an addiction to disappointment"
I used to get myself wound up and pretty tightly over my work an wanting it to be perfect, now not so much. One of the things I've come to realize is that once a piece is done if I don't like it a year later it's ok to change the work or even destroy it, but by striving for perfection I would never finish the piece.
We can remain stuck and live with continual disappointment or we can move forward declare it done and create more works of art.
