"People have writer's block not because they can't write, but because they despair of writing eloquently."
"The writer who cares more about words than about story (characters, action, setting, atmosphere) is unlikely to create a vivid and continuous dream; he gets in his own way too much; in his poetic drunkenness, he can't tell the cart--and its cargo--from the horse."
"A book worth reading only in childhood is not worth reading even then."
"Unlike politicians, storytellers know that you cannot sever reality from reality: all you are entitled to do is to re-imagine the world in order better to see and understand it."
"You never learn how to write a novel. You just learn how to write the novel that you're writing."
Gene Wolfe, paraphrased by Neil Gaiman
"You can take for granted that people know more or less what a street, a shop, a beach, a sky, an oak tree look like. Tell them what makes this one different."
