Tiny, regarding whether your mind and your horse's mind are in sync.
I had an interesting experience years ago with Spike, my heart horse, the one in my avatar. This was about 16 years ago, when I first got him.
Back then, he was a nice boy, but very introverted. He had never really been mistreated, but never been really loved either. He was very uninterested in things, generally. At the time, we were doing a lot of riding in a small paddock, about the size of a large arena. He would walk and trot fine, but would only canter a few strides before slowing again. I tried everything I knew at the time, which was basically just squeeze harder, lean forward, and shout encouragement.
After a few weeks of this, I was getting very discouraged. My first horse, wont even canter?
So one day I went home, and just sat there and envisioned us cantering around the whole paddock. I 'saw' us do it, again and again. Next day, driving out to the barn, I imagined it again.
And yes, as soon as I mounted, we took off on a beautiful canter all the way around the paddock. Then we did it 4 more times! Lol
So what was different? My cues? My body language? I don't know. I like to think that maybe he picked up on my brainwaves, and he saw it too.
Lol, anyway, that is my true story about my mind and my horse's mind finally being in sync. :)
