“The leader is one who knows with greater than average strength of intuition what he wants to get done and where he wants to go. 'The world stands aside to let pass the man who knows whither he is going.'
This means that he possesses clarity and precision as to the objectives, purposes or aims that he desires for himself and his group, and that he holds these deeply enough and permanently enough to see them well on the way to being realized. Purposefulness to be effective requires that the aims are: (1) definite; (2) readily communicable to others; (3) potentially attractive to others; and (4) vigor¬ously, persistently and enthusiastically sustained by the leader.”

He that knows not what the world is, knows not where he is himself. He that knows not for what he was made, knows not what he is nor what the world is.

Context: The scene should be gently open'd, and his entrance made step by step, and the dangers pointed out that attend him from several degrees, tempers, designs, and clubs of men. He should be prepared to be shocked by some, and caress'd by others; warned who are like to oppose, who to mislead, who to undermine him, and who to serve him. He should be instructed how to know and distinguish them; where he should let them see, and when dissemble the knowledge of them and their aims and workings.
