Learning how to Learn
I find the way most people offer information to the horse is with an expectation of tolerance by the equine.
Rarely is there any consideration for being able to influence the horse's focus, redirect his thoughts, help him let go of physical tension, or have many of the other tools needed so that he can learn how to think through the unfamiliar, rather than just tolerate it.
Why does it matter?
Because each interaction you're teaching the horse to either become more weary and distrustful of the human experience, or you're increasing his curiosity and building his confidence for all that you ask of him in the future.
The real motivation, even without acknowledging the horse and what he is experiencing, might come from asking oneself, "Wouldn't it be easier to set the horse up for success from the start, rather than having to undo unnecessary traumatic experiences and dangerous coping behaviors created because of hurried, unclear, and lack of quality human communication?"
