Has my horse made me a better rider?

I would say that the answer is yes! Difficult horses can improve your riding immensely. I used to ride a spazzy ex-Reiner and my seat was awful beforehand and I came unseated pretty easy. After going through countless spazzy moments with him, I've discovered I'm pretty good with horses who are "go go go go!!!!" if you touch them with your leg. Now that I'm training a green broke. 4yearold, Ive noticed I'm riding even better. But two notes: IMPORTANT-do NOT let your ego get out of control because of this. Everybody, no matter the level, has room to learn. :) this is totally unrelated but I love Arabs. :D
