TAURUS (April 20-May 20): “Use your enemy’s hand to catch a snake,” advises a Persian proverb. Store that bit of wisdom in the back of your mind, Taurus. It may come in handy between now and the solstice, which should constitute one of the most interesting adversarial seasons in years. Here’s another counsel to guide you during this serpentine time: “Love your enemies. It’ll drive them crazy.” Perhaps the most useful epigram comes from Havelock Ellis: “Our friends may be the undoing of us; in the end it is our enemies who save us.”
