Wait on it? For how long? Days? Months? Years? It's not forcing anything. It's getting a result and showing the horse what you want since she's either stubborn or unsure of what's being asked of her. The OP can then go back and ask again with lighter aids to re-enforce the training. Horse's can only learn from their trainers. If their trainers just sit there until the horse decides to make a decision on its own, that's not training and it's not even safe. Let a horse make a decision in one area and it will start making decisions in others.
