The basic first step of learning anything requires curiosity and interest, and Mercury meets that requirement. However, when it comes to learning at a deeper level, such as scientific research or invention, Mercury alone cannot handle it. Nevertheless Mercury is essential for any type of learning. The basic quality of observation, followed by logical interpretation of the observation, sharp analytical mind, general commonsense, and a keen sense of presence of mind are the attributes of Mercury. Mercury controls speech and power of speech.
Mercury loves to be a communicator, business sales person, or a spokesperson for a dignitary.
Mercury plays a tremendous role in influencing the public opinion. Mercury rarely leads, but is best suited to be an advisor to a leader. Another great quality of Mercury is his wittiness. Comedians, story- tellers, and magicians usually have properly placed powerful Mercury in their birth charts either in Gemini or Virgo. Because of its dual nature Mercury tries to see both sides of an issue with equal vigor.
