"What does being a writer mean to me? It means simply being true to my imagination. When I write something, I think of it not as being factually true (mere fact is a web of circumstances and accidents), but as being true to something deeper. When I write a story, I write it because somehow I believe in it -- not as one believes in mere history, but rather as one believes in a dream or in an idea." Jorge Luis Borges, This Craft of Verse.
In a creative writing exercise on a school visit, a student was stunningly true to his imagination. He told me the most precious thing he could imagine was:
"the stone of souls: to look at it is like looking at pure sunlight, to touch it sends a shiver down your spine."
