I found another great quote, this time from an artist.  I think it deffinately describes what most artists feel, at least its the way I feel, when working on something.  It even applies to just any project that some one is doing, something that they enjoy doing or just put a lot into.  I found this one on my calander.  It funny where you come across wisdoms and such.  Just goes to show, that if you keep your eyes open and pay attention in life, you'll find some great things.
