Think like a horse

If you were a horse your happiest moments would be secure, unchanging and in a herd. 
They are prey animals, as oposed to predators like us (even vegetarians!).  Their survival depends on following the herd leader with unquestioning obedience.  In nature, if the herd leader says, "Run!" they must do so immediately or the consequence might be death.
Our domesticated horses are not evolutionarily far from this sentiment.  That's what makes them trainable.  The desire to obey and be "with us".  When we ride, we are a herd of two and it is imperative that the rider is the herd leader.  Otherwise, our mount loses confidence which can produce undesirable behavior in many forms.
Think like a horse and take charge (with kindness of course!)
