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.
If you want something, you must have it, and no one can stop you -- not even sweet Reason herself. Learn to look before you leap, which is good advice whether you're a Horse or a Lion, but especially good advice if you're both in one hot package. Beware the vice of false modesty -- it is a failing to which you are prone!
