Mercury Retrograde and Zodiac Signs

When Mercury is in retrograde, its influence depends on which of the 12 zodiac signs the planet is in when it goes retrograde. Below is a brief look at what to expect:

IN ARIES: Expect to be frustrated and frazzled. Assertive,
 impulsive Aries wants to move
 ahead, and all of the energy is going backward. Watch what you say and how you say it. Pay attention to what people say to you; you might be pleasantly surprised.
IN TAURUS: Take time to formulate your thoughts. Taurus, an unhurried sign, slows down the
mental processes. He also governs banking, so delay money matters. Review financial matters, and position yourself for growth.
IN GEMINI: Because Gemini
rules communications, be prepared for miscommunications
 when Mercury is in this sign. Expect lots of phone calls or none, and lost or misplaced mail. You may not articulate clearly, and gossip abounds. Old friends may reconnect.
IN CANCER: Expect annoyances 
at home with baking, gardening,
 and household duties under domesticated Cancer. Complete repair projects that weren’t finished or done correctly.
IN LEO: Avoid speculative investments. It is not a good time to
 buy and sell or do any trading.
 Instead, analyze your investment
 portfolio. Use your know-how and advisory skills to help friends and associates.
IN VIRGO: Challenging situations arise, especially in the 
workplace. Expect product delays and equipment breakdowns,
 as well as crankiness among coworkers under finicky, detail-oriented Virgo. Double-check your work before you call it finished.
IN LIBRA: Accept your physical
 attributes; do not have a makeover. Indecision reigns, so limit
 purchases—or risk returning
them. Libra, representing beauty, grace, charm, and diplomacy, is out of balance. Refresh, relax, and rejuvenate.
IN SCORPIO: Emotions rule—not common sense—so beware.
 Avoid affairs of the heart. Passionate Scorpio is also secretive,
and your secrets may seep out. Keep them in a diary.
IN SAGITTARIUS: It is not a time 
to travel, so reschedule or expect
 delays, lines, and lost directions.
 Instead, take care of local affairs.
 Patience and a sense of humor are needed.
IN CAPRICORN: Avoid buying, 
selling, or renting real estate un
der Capricorn, the sign that governs property matters. Expect
problems with paperwork, packing, and movers. Reunite with family or vacation at home.
IN AQUARIUS: With Mercury retrograde in Aquarius, the sign 
that governs relationships, 
friendships are put at risk. Petty
squabbles, misunderstandings, and miscommunications abound. Know who your friends are.
IN PISCES: Foggy thinking,
 daydreams, and escapism are 
the norm; day-to-day realities
 confound otherwise clear heads
when Mercury, the planet that rules logic, is in Pisces, which governs illusion. Practice creative pursuits—writing, dancing, photography, film, or painting.
