"Zest. Gusto. How rarely one hears these words used. How rarely do we see people living, or for that matter, creating by them. Yet if I were asked to name the most important items in a writer's make-up, the things that shape his material and rush him along the road to where he wants to go, I could only warn him to look to his zest, see to his gusto."
-- Ray Bradbury 1973
