The causes for uncertainty as to work are many and varied. And yet all the many causes can be traced to two fundamental deficiencies in human nature which are but poorly supplied in our traditional systems of training and education. The first of these is, of course, ignorance--ignorance of self, ignorance of work, ignorance on the part of parents, teachers, and other advisors; ignorance on the part of employers. As a race, we do not know human nature; we do not know how to determine, in advance of actual, painful and costly experience, the aptitudes of any individual. We blunder a good deal even in trying to learn from experience. We do not know work; we do not know its requirements, its conditions, its opportunities, its emoluments. And so, in our ignorance, we go astray; we lead others astray. We neglect important and vital factors in human success and happiness because we do not know how important and how vital they are. Our ignorance of their importance is due to our ignorance of human nature and of work. A second cause for our uncertainty lies in the almost universal human habit of purposelessness. Drifting, not steering, is the way of nearly all lives. It is hard mental work to plan, to consider, to study, to analyze; in short, to think. Someone has said that the average man would rather lie down and die than to take the trouble really to think. It is easier to await the knock of opportunity than to study her ways and then go out and capture her. She treads paths which may be known. She has a schedule which may be learned. She may thus be met as certainly as by appointment. Those who await her knock at the door may be far from where she passes. We in America, especially, place altogether too high a value on our ingeniousness, our resourcefulness. We therefore put off the evil day. We say to ourselves: "There is plenty of time. I'll manage somehow or other when the time comes for action." We are rather proud of our ability to meet emergencies. So we do not plan and take precautions, that emergencies may not arise. It is too easy to drift through school and college, taking the traditional, conventional studies that others take, following the lines of least resistance, electing "snap courses," going with the crowd. It is too easy to take the attitude: "First I will get my education and develop myself, and then I will know better what I am fitted to do for a life work." And so we drift, driven by the winds of circumstance, tossed about by the waves of tradition and custom. Eventually, most men find they must be satisfied with "any port in a storm." Sailors who select a port because they are driven to it have scarcely one chance in a thousand of dropping anchor in the right one.
