When I received my first horse, I really didn't know what I was doing. I did have a trainer right there and she helped me a lot. There's one thing though that I mis-taught? My horse. He flexes behind the vertical when I ask him to collect. How does one fix that? Or is it even possible?
When we ride on the property he's got enough energy/spunk that when I boost his engine and hold the front, he does it perfectly. But if he's totally relaxed in the arena, he curls his neck in a circle.
