I once knew an artist who painted portraits that were widely acclaimed but in midlife he suddenly switched to making glass boxes with rocks in them, just ordinary rocks that to him looked meaningful in a particular arrangement. Nobody else ever liked the rocks, even his wife didn't like them, and after a few years he went back to portraits without having gotten anyone to see what he saw. Now, whenever I try to do something really different in my writing, I think, "Is this my rocks?"
