Aiming high is recommended when one sets goals. Getting from Point A to Point B may be easy, but aiming high ensures that Point B comes as naturally to you as it could. If you set your goal against Point B, but set yourself out to aim for an area beyond that, say, Point C, then Point B would be easier to manage as a matter of principle.
