Manipulation, anyone? The Scorpio side of you is always out for number one, and the amazing quality of your self-aggrandizing tactics is that you so often get away with it by means of your Rat-induced radiant personal magnetism. Direct and forthright, you manage to defuse animosity by making no secret of what's in the deal and for whom. Others can respect such a straight-talking competitor; even if the Rat/Scorpio's concomitant razor-sharp wit and acid tongue can sometimes keep potential allies at bay unless kept in careful check.
Playing the game of patience is not the strong suit of the Horse/Leo, but what you will not allow it to teach you, the trial-and-error method might succeed in forcing through the wall of your indomitable will. After you've had the worst of it a few times, perhaps then you'll learn the value of forethought and careful preparation. In the meantime, you'll simply forge ahead Horse-style, winning some and losing others, but with more wins than losses due to your phenomenal Leo charisma, not to mention your single-minded devotion to your goals.
