We are getting better at polo. Juliano learned quickly to follow the ball but not to go directly over it. We practice polo with just savvy string on J's neck. J treats his responsibilities seriusly: don't change gait, follow the ball.
I must say that for me polo has proven to be a great way to practice focus. When you sit on a horse and you want to go to the ball you simply have to focus on it. Your body automatically turns towards the ball, the eyes on your shoulders, knees and bellybutton as Linda often says do the trick. You don't have to imagine a point on the ground, which is also great but you can easily get distracted or if you land near the spot you think "Oh well, good enough". Here you have to get to the ball, hit it and than again travel point to point.
