One of Two Ways to Face Life

There once was a beautiful valley where a herd of horses were kept. In that same valley, just a little ways off, donkeys (jackasses) were also there.

At night coyotes would come down into the valley, and when morning came, most of the donkeys were found badly injured or dead. Not one of the horses were hurt.

When asked why the horses were spared or unharmed, the keeper of the grounds responded, "At night when the coyotes arrive, the horses put their heads together and kick the coyotes. The donkeys face the coyotes and kick each other."

Which one am I?
