There are a great many careers in which the increasing emphasis is on specialization. You find these careers in engineering, in production, and in teaching. But there is an increasing demand for people who are able to take in a great area at a glance, people who perhaps do not know too much about any one field.  There is, in other words, a demand for people who are capable of seeing the forest rather than the trees, of making general judgements. We can call these people "generalists".
    The specialist understands one field; his concern is with technique and tools. He is a "trained" man; and his educational background is probably technical or professional. The generalist deals with people; his concern is with leadership, with planning, and with direction giving. He is an "educated" man; and the humanities are his strongest foundation. Very rarely is a specialist capable of being an administrator. And very rarely is a good generalist also a good specialist in a particular field. It is your task to find out, during your training period, into which of the two kinds of jobs you fit, and to plan your career accordingly.
    Your first job may turn out to be the right job for you—but this is pure accident. Certainly you should not change jobs constantly or people will become suspicious of your ability to hold any job. At the same time you must not look upon the first job as the final job; it is primarily a training job, an opportunity to understand yourself and your fitness for being an employee.
