ARIES (March 21-April 19) Much of the reader mail I receive is friendly. But now and then I'll get a message like this: "I've followed your horoscopes with pleasure for years. But I must say, you've really lost it lately. I can't stand the garbage you've been slinging. What happened to you?" My response is to wonder why the person never wrote to me while he was happy with my efforts. It reminds me of a quote by Leon Uris: "How often in life it is that we have no time for our friends but all the time in the world for our enemies." It also reminds me of how tempting it is to focus on what repels u s and scares us, shortchanging the dreams that excite us. Your assignment in the next four weeks, Aries, is to reward what you like and pursue what you want. For now, forget about what you don't like and don't want. TAURUS (April 20-May 20) The worst painting in history is hanging in San Francisco's De Young Museum. It is "Noel and Bob" by Joan Brown. It's so awkwardly garish and trivially monstrous that I can only conclude Brown possessed what might be termed "negative genius." It's not just that she had no talent. She actually had the opposite of brilliant talent. And yet I must confess I had a good time gazing at this anti-artistic botch. I thoroughly enjoyed laughing at it, and was quite pleased at the jokes my companions and I made about it. I suggest that in the coming week you try something similar: enjoying the entertainment value and educational merit of clumsy, ungainly, out-of-whack stuff. Doing so will sharpen your wits for the not-too-distant future, when you will come into proximity to a lot of understated beauty and elegance and grace.
