Do yourself a favor and read this very short post from Seth Godin on striving for perfection. As designers and creative professionals, we struggle with this. When do we let go of a project? When is a project complete? In my experience, a project is never perfect and I don't think I've ever finished a project that I didn't want to change the minute it was done. I'm particularly bad about holding onto typeface designs until they are perfect... and the end result is that they are never finished.
Anyway, a good thought to take into a crazy Monday.
