This is definitely true in the case of some of my horses. I have had a difficult horse and he turned out amazing. I'm now working with another horse who is even worse and I'm sure he'll have equally as much to offer
Shooter does this to me ALOT! lol Most the time when i'd go out to catch him to go rope, he'd take off so i'd give up. He'd run to the end of the pasture, then run back to the gate. Mom always says he will decide when he's ready to to go lol :)
"I don't care if your trip was a shoe-in for champion, or you got disqualified at the first fence. You walk out of that ring, pet your horse and thank him for not killing you because you know damn well he could have.
