When Mercury is in retrograde, it causes indecision and changes in plans, thus these retrograde periods require caution and orderly thinking. Retrogrades are a good time for research, planning, and taking stock of things, and are excellent times to finish projects already begun, especially those that have been put off.

In general, you thus should avoid beginning projects while Mercury is in retrograde. New projects should be postponed until Mercury is again in direct motion. This is because projects begun during a retrograde often develop differently than expected, which may lead to disappointments and disruptions. This is most noticeable in business matters, especially communications and transportation.

While Mercury is in retrograde, it is most important to give attention to the details and the daily routine.
