PISCES (Feb. 19-March 20): Author Robert Louis Stevenson loved the work of poet Walt Whitman, regarding him as an unruly force of nature and "a large shaggy dog, just unchained, scouring the beaches of the world and baying at the moon." Your assignment is to do your best imitation of a primal creature like Whitman. In fact, consider being him for Halloween. Maybe you could memorize passages from Whitman's "Leaves of Grass" and recite them at random moments. Here's one: "I too am not a bit tamed, I too am untranslatable, / I sound my barbaric yawp over the roofs of the world."
