Mercury, the planet of communication, turns retrograde in Aquarius on 11th January until the end of the month. Communications of all forms are prone to disruptions so be sure to back-up your computer files, double check your traveling schedule before you leave the house, use your words carefully to avoid misunderstandings and read the small print before you sign anything.
Fortunately, this period is not all doom and gloom. It is the perfect time to review, revisit and revise any projects you have been working on. In Aquarius, it encourages breaking away from old habits and limited thinking. The exact nature will depend on the placement of your Mercury in your natal chart.
