The true measure of power is not how strong a blow you can strike, nor how great a foe you can defeat. The true measure of power is accomplishing your goals.

[For all her own ability in battle, she hasn't the power to accomplish the full spread of her goals... assuming, perhaps, that she wants to any more. So she understands.]

If your goal is to do this properly, it will take more power than if you simply struck out without restraint. Is that truly 'holding back'?
