My horses enjoy pleasing me, they respect me because I respect them. They gallop up when I call them and when a scarey thing pops up they know its OK to be afraid but they also know its not Ok to leap away or bolt off because I'm there to tell them not too. This is doesnt done by force or game playing its just down to firm fair handling and caring
I do agree that all horses have different personalities though, every foal we bred was born different - even foals with the same parents were rarely the same.
You can't treat all personalities the same though, that's like trying to mould them into something they aren't - some need more time than others, some need a firmer hand, some need a really sensitive approach, some need loads of stimulation to keep them from getting bored. You try and treat them all the same and that's a recipe for disaster. That's like getting on every horse you own and expecting to ride it in the same way. Doesnt work like that
