The last of these fundamental considerations of man, and by far the most important to the personal success of any leader, is an appreciation of what his _own personality_ means for success or failure in the effect it has upon his fellows. In some way it should be possible to make each man realize the truth of this, and thus give it due consideration. The leader responds to the fact that he must learn how to use his human-being tools, yet often ignores the equally important fact that he has to use these tools through the instrumentality of his own personality. His ability and success will largely depend on how this personality of his impresses others, on how it affects these sentient tools. His purpose and character, his personal bearing and manner, the tones of his voice, his habits and way of looking at things--all the manifestations of his personality are more or less important influences in determining his ability to handle others. Yet the average of leaders not only accepts himself complacently as he is, but actually ignores the advantages of even finding out what he is, let alone trying to improve himself. The progress of the race depends upon the development of the individual--albeit in co-operation with his fellows. In consideration of this fact nature apparently designed man to accept complacently his own personality and thus be content to use and develop it without being discouraged because he was not as some other man. It is certainly true that we rarely find a man who would exchange his personality for that of another. But nature never intended this complacency to go to the point of ignoring all possibility of improvement, and even of failing to use understandingly the personality one does have. The great trouble with mankind is that they generally see themselves only as they are reflected in the near-by mirror. They rarely get the perspective of themselves as they really exist in the life around them; and so they miss the benefit of measuring their egos by comparison with the realities of life. It would help us all "to see ourselves as others see us." We could then learn each how to use his personality advantageously from seeing how it affected others, and we would then lose some of our arrogance from seeing what unimportant individuals we really are after all. It is good for the soul of any man to visit some height like the tower of the Woolworth building and thence view humanity on the earth below him, hurrying to and fro on its self-important business. These humans then appear of about the size and importance of ants, and the spectator is lead to realize the unimportance of any one individual man in comparison with the world about him, and to wonder just how big he himself really appears to the distant Eye of Omnipotence. He may thus develop a wholesome humility which may lead him to fit himself to play his part more reasonably.
