TAURUS (April 20-May 20): My Taurus friend Allie just put a new bumper sticker on her car: “I can’t remember if I’m the good twin or the evil one.” It’s almost as if she intuitively guessed one of the key themes you Bulls will soon be wrestling with: how to tell the difference between your strong, beautiful, inspiring qualities and your unripe, unlovely, and debilitating ones. It won’t be as easy as you might imagine. There are sides of your personality that are a blend of both the good and the bad, for one thing. It’s also true that your virtues sometimes mutate into vices, and vice versa. Proceed on this exploratory mission with a tough but open mind.
