Mars, the planet of willpower, enters the zodiac sign of Libra on Oct. 22. This will change the balance of power in your relationship. Mars doesn’t do this to wreak havoc in your life. Mars does this in order to test your mettle. If you’ve always been the leader then it’s time to share the power. If you’ve always been a follower then you need to step up to the plate. There’s always a “man up” quality when Mars is traveling through a cardinal sign (and this applies to women as well) but it’s in service to invigorating your relationship and making it the best that it can be. Mars is the planet of camaraderie after all. And as for those relationships that are found wanting or don’t make the grade? They will be jettisoned unceremoniously. Mars will be in Libra from Oct. 22 to Dec. 9.
