I was not actually criticizing your riding in the video.. I was just offering up something to help you better train this horse. No matter how experienced you are, lessons can help you. I trained a pile of horses and then would go and take a few lessons when I could. Fresh eyes and all that sort of thing. ;)
I know.. we all say we won't ever sell.. but if you have a severe head injury you will be in long term nursing care and have no choice. I had a nephew with a severe head injury and believe me.. you won't ever be the same person again. But that is NOT what is going to happen to you!
One other thing.. if you can build a mounting block you can get on and ride without your feet in the stirrups for a few rides. When getting on a really green horse like this I always tried to avoid using stirrups to mount and dismount because if you get hung up it can go bad real fast. When I got off I never stepped down with a stirrup. I took both feet out of the stirrups and then dismounted by swinging my leg over and my body around. Saved my butt a few times.
The getting on and getting off using the stirrup sets you up to get hung up and it also twists the saddle out of shape over time.
I trained a lot of horses. I just want this to go smoothly for you. You got a nice horse there.
