A man who wants to get in shape and has read the best bodybuilding books will get nowhere unless he applies that knowledge in eating healthy food and working out daily. That takes sustained willpower. In time, if he’s faithful to the practices necessary to achieve his goal, the man will start to love eating well and exercising so much that he is not pushed toward doing so by willpower but rather drawn to it by love. He will have trained his heart to desire the good.
