Broncos were once a symbol of the vast American western region. A bronco is a wild and rough horse, so if a person rides on or burdens it with a load, it jumps up and down. So, when people used a bronco, they had to tame it. In order to tame a bronco, cowboys mounted on the bronco and subdued it, which has been developed into rodeos today.
Another way to tame a bronco is to tie it to a donkey. If the two are tied together on the grassland, at first the weak donkey will be dragged on by the wild horse running around. Surprisingly, however, the bronco, which acts as he pleases, will follow the donkey gently in a few days. No matter how desperately the horse tries to separate the donkey, he finally comes to know that it’s of no use and gives in to the donkey.
A person with a rough character is often referred to as a wild horse. Everyone has some rough personality traits. We need to put a donkey beside a wild horse in us. The donkey in our hearts, which tames us to be gentle, is perseverance.
