Every man should feel sure that his suggestion will be fairly considered and, if his idea has real value, that he will be given full credit all the way up the line to the big chief. And the way to do this is to take the man in person to higher authority and have him personally explain his idea. This makes very real to him and his fellows his importance as a member of the team. If in a big business concern the man were actually called before the board of directors to explain the details of some improvement he had thought out, nothing could do more to establish a sense of partnership in the undertaking. Appreciating their value, you can make as much as you will of every opportunity thus to increase the men's interest in the work and their sense of co-operation. _Advantage of Ambition._--Ambition for advancement is another of the human instincts to be considered by the leader both in connection with his own career and in handling his subordinates. Every one should feel that he may progress as far as his actual ability warrants--and he certainly may, for good leaders are still rare and to be desired and the truest saying of life is that there is plenty of room at the top. But subordinates must realize that selfish ambition cannot win, that it is only by playing for the team and working for the best interests of the whole outfit that one can win his superior's recommendation for promotion. The unselfish ambition of an individual thus improves both his chances for promotion and the work of the team. Industrial progress and individual promotion both spring from individual effort to increase output or to decrease expenditure of energy. It is generally true throughout industry that "the great stream of intelligence, inventiveness and adaptation flows from the bottom up and not from the top down, and that the top is continually being recruited from the bottom," as employers daily graduate from the classes of laborers. This latter is so common a fact that it is frequently overlooked. It is so wholesome a fact, so characteristic of our democratic institutions and so helpful a thought in times of unrest and discouragement, that it should be emphasized and frequently brought to mind.
