I am not at all suprised that would be the case, as he is a very opportunistic horse. I finally got the confidence to be outside of the arena. Inside the arena he would get bored real quick and started acting up and just would not go. Yesterday I lunged him, then ground drove him for about 15 minutes and didn't even plan on getting on him. But if I plan on riding I usually get so worked up that I can't even bring myself to do it. So I thought I would just sit on him, then decided to ride around a little bit. But I was even more tenative because I wasn't wearing a helmet. (Which if I did fall off I could still hurt myself whether wearing a helmet or not, but it just gives me that little extra push to get on.)
But after fixing my own mindset how should I get him going? Or would you think that simply fixing my own attitude would fix most of the problem?
