The key word with you is loyalty. No one will ever be able to pull the wool over your eyes -- you'll see through them like cellophane every time. Combining as you do the unflappable calm and rock-solid strength of the Bull with the Rat's nervous intellect, you are a living testament to the efficacy of strategy, in love as in business.
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.
