Saturn in Sagittarius changes things. In Sagittarius, Saturn will indeed change the way we think about the world. Because of a trine to Uranus, independent thinking is promoted, evolved, through trials. The square to Neptune can indeed create self doubt and deception, and as we realize that we can't trust others, we must learn to trust ourselves.
The eclipses fall in Pisces (Solar - March 20), in Libra (Lunar - April 4), in Virgo (Solar - September 12) and in Aries (Lunar - September 27). The Eclipse in Libra is the most intense of all, opposing Uranus and squaring Pluto.
The last square between Pluto-Uranus takes place March 17, and hopefully the relationship between these two planets are less tense thereafter.
Mercury is retrograde 3 times, in air signs, fist in Aquarius (January 21 - February 11), second in Gemini (May 18 - June 11) and third and last time in Libra (September 17 - October 9).
May is the most difficult month, when planets in Cancer/Gemini oppose Pluto in Capricorn and Saturn in Sagittarius. There are also squares to Neptune in Pisces and Uranus in Aries. Plots, lies, manipulation, aggression, conflicts is the result.
The summer is interesting in itself, with Saturn reentering Scorpio June 15 - September 18. Venus is retrograde mainly in Leo July 31 - September 6. Venus retrograde usually brings reevaluation of relationships. Saturn back in Scorpio helps us deal with some unfinished business.
