I love story-writing because I can (more or less, on occasion) actually DO it. That's really the truth. I like the idea that a story is sort of a site for making cool language effects - a site for celebrating language, and, therefore, the world. And the brevity is part of the challenge. I like stories because I get them - I know how to make beauty, or something like beauty, in that mode.
If you really think back to the great writers, there's a lot of happiness in Tolstoy; there's a lot of love, there's childbirth, and there's dances. And likewise in Shakespeare and even Cervantes, there's a lot of celebrations of the positive manifestations of life. Technically, I found it harder to do, so that's kind of a good late-life challenge - without getting sentimental or chirpy.
One of the inspiring things about Susan Sarandon career is that there's a quality of real fearlessness in it - you seem to be in it for the challenge and the experience.
