You'll be making the switch from minnow to shark when Mars enters your zodiac sign on March 22nd. Named after the Roman god of war, Mars has a take-no-prisoners approach when it comes to getting what it wants. This may surprise loved ones and friends (what happened to their guppy friend?), but it will also make enemies think twice about messing with you. This will come in handy when you have to lay down the law with people who think that they can browbeat you into doing what they want regardless of your concerns and feelings. They are about to have another “think” coming.
