Your horse can’t understand the English language so if someone insults your riding you are the one who can choose to listen to it or ignore it, and your horse won’t care, either way she’ll/he’ll love you no matter what.
We all started on the most bombproof horse in the world. Don’t forget that you used to pull to hard on the reins. Don’t forget at one point you were scared to go fast. Don’t forget your first fall. Don’t forget your first jump. Don’t forget your first horse. Don’t forget that at point you were tiny and couldn’t throw the saddle up. Don’t forget it for a second. Don’t forget where you came from.
