My creative habit: I've been working on my textile art for most of the week -- cutting, stitching, painting, screenprinting -- and have been starting each day with a few pages from Art & Fear, by David Bayles & Ted Orland. One little chapter is enough to chew on for a whole day. Some of my favorite insights so far:
Most artists don't daydream about making great art -- they daydream about having made great art.
The function of the majority of your artwork is simply to teach you how to make the small fraction of your artwork that soars.
Making art provides uncomfortably accurate feedback about the gap that inevitably exists between what you intended to do, and what you did.
Vision is always ahead of execution -- and it should be.
Art is like beginning a sentence before you know its ending.
(Obviously, I have been dwelling on all the projects started, how they're proceeding, new projects I can't get to yet, and why all of it never looks the way I thought it would when I started!)
