Do you inspire your horse? Does he volunteer more than you ask? Are you proud of who you are in his eyes?
And yes, this is a donkey. There is no better trainer for a human who wants to work with horses. Look him in the eye. You are out-matched in strength and wits. Don’t just lay your ego down. Lay it down, walk over it a few times, and then spit. If you feel confident that you’ve succeeded in defusing your ego, then repeat the process until you stop judging. Quantify nothing.
