A full reading for Rat × Capricorn meeting Monkey × Sagittarius is on the way. In the meantime, the score above is computed from the canonical element matrix and sign-cycle distance, and the profiles below cover each side individually.
Power for its own sake, and the cold brutal solitary serenity that accompanies such an exalted position, are precisely what the Rat/Capricorn lives for. If they think they've seen goals-oriented people in action before, they haven't seen anything until they've seen the Rat in you breeze past them on your way to the top, in such a way as to make Genghis Khan seem mild-mannered, of whatever hierarchy to which you see fit to belong.
Try to forget the capricious passions of your wayward youth -- that's all in the past now. The Monkey/Sagittarius' fundamental rebellion against the time clock has continued, however, and you are better off in a less structured job environment, perhaps running your own small business, or going in for freelance assignments; telecommuting was made for the Monkey in you.
