When I walk up to a horse, I like for them to turn around and face me and not walk away. Get you horse in a round pen or corral, and take the halter off. Leave him in there for awhile and let him think he has been "turned out". Now approach him with the halter in full view, when he begins walking away from you, make him work, get him going the direction he walked away from you in. Let him work for awhile and then try approaching him again. If he walks aways, repeat and start working him again. Keep this going and when that horse gives even the slightest glimpse in your direction, looks towards your or stops and turns toward you, drop your head and walk backwards away from him. Then he see facing you and walking towards you, halter or not, as a release of pressure. This takes a little patience and maybe a little time, but it has never failed me. I've used it on spoiled, hard to catch horses and horses that have never seen a human before. Either way it works.
