In an effort to shake up my attitudes about it somewhat, I've taken an interest in books about creativity, and have lately been reading Sweat Your Prayers, which is good.
Some others on my shelf or on my wish list:
The Artist's Way
Women, Creativity and the Arts
Drawing on the Right Side of the Brain and Drawing on the Artist Within
Undressed Art: Why We Draw
Anybody have any other suggestions or comments on the books?
