Gee, horse lovers, I'd be happy if my horse liked me and didn't shy at stuff
The good news is that no matter where you are at in life [or animal training] there is always more to learn and new places to go. The bad news is that there is always more to learn

You are never done.
The other good news is that we don't have to be Stacy because, although we can all dream the impossible dream, most of us will just be on the trail to the impossible dream and not actually managing to accomplish the impossible dream. Luckily, life is about the journey, not the destination.
