If anyone here is having an art block, read Twyla Tharp's excerpt, "Spine", from her book The Creative Habit. I was kinda in limbo for a while 'til I read the excerpt, and it helped me get back on track. Personally, I think it's especially helpful for perfectionists who get kinda lost in the creative process after a while.
