Taming the horse

Once upon a time, 
there was a rider -
who bought a horse,
Failed to tame it - 
shot it in the end.
Bought another horse, 
this time left it to wild.
After several dead and
multiple feral horses -
it flashed to him -
It is not he who is trying to tame -
rather the horses are testing him.
he failed them miserably.
He no longer needed to tame any - 
Now he could ride any horse.
