And this is why writing good fiction is almost never easy. The point at which fiction seems to become easy for a writer--and I'll let everyone supply his or her own examples of this--is usually the point at which it's no longer necessary to read that writer. [...] It's a prejudice of mine that literature cannot be a mere performance: that unless the writer is personally at risk--unless the book has been, in some way, for the writer, an adventure into the unknown; unless the writer has set himself or herself a personal problem not easily solved; unless the finished book represents the surmounting of some great resistance--it's not worth reading. Or, for the writer, in my opinion, worth writing.
