Mars, in Greek mythology is also known as the warrior. Its aggression combined with the bluntness of Sagittarius, where it travels to, can make one assertive and bold; at times aggressive. Even the introverts might be caught speaking their mind during this period. Leadership skills are at their peak for most. This period is good for lawyers, teachers and journalists as their conversational powers are enhanced during this transit.
However, be a little cautious till the shadows of Mercury retrograde decline from January 12th. Though Mercury goes direct from January 7th, the shadows will linger on till January 12th. Therefore, miscommunication and misunderstanding are possible. Prevention and precaution are advised for all zodiac signs.
