man who had served him satisfactorily for years without a word of warning, and without a hearing. Unless you understand human nature, and if you are at all responsive to appreciation, there is probably no greater pleasure than to work for such a man as we have described, so long as the sunshine of his favor falls upon you. But, as a general rule, we find their employees anything but happy. Almost without exception they feel that their tenure of office hangs by the slenderest of threads and that it is necessary to regard all of their fellow employees with suspicion. Some men enjoy working in this fevered atmosphere. If you are one of them, there are excellent opportunities for you in the employ of a man of this type. But you will do well always to have a good safe place prepared in which to land if you should suddenly be dropped. THE BLUFFER In all of your dealings with the man who lacks real courage, remember that his blustering and show of bravery is only an assumption to cover up his deficiencies and that if you yourself have the courage to face him and, in the language of the street, "to call his bluff," he will quiet down and be perfectly amenable to reason. But be sure to observe your man carefully and accurately before trying to call his bluff. SUCCESS AS AN EMPLOYEE The ultimate success of every employee depends, first of all, upon his selection of the kind of work for which he is pre-eminently fitted; second, his selection, so far as possible, of the kind of employer and superior executive under whom he can do his best work; third, upon his study and mastery of every possible resource of knowledge and training connected with the technical and practical aspects of his work; fourth, upon his careful and scientific development of all of the best and most valuable assets in his character; fifth, upon a thorough understanding and application of the principles of personal efficiency; sixth, upon an accurate knowledge of the character, disposition and personal peculiarities of his employer or employers and superior executives; seventh, upon an intelligent and diplomatic adjustment of his methods of work, his personal appearance, his personal behavior, his relationship with his fellow employees and with his employers, to the end of building up and maintaining permanently the highest possible degree of confidence in him and satisfaction with his service.
