Mercury conjunct Venus
From Astrology In Depth
Mercury conjunct Venus reflects a love of socializing and (at least) mental sharing. One becomes more apt to appreciate the qualities of others.
This aspect can add some objectivity through a developped willingness to listen to what others have to say, although what one would take from it depends upon the temperament of Mercury and possibly other considerations in the chart. It thus can advance one's understanding, although it may make one less competitive intellectually, unless Mars is also strong or there are other competitive indications.
