best in engineering who are medium in texture.  The fine-textured individual, however, if he is qualified for engineering, will take up some of the finer, higher grades of it and make fine and delicate material or machinery, or will engage in some form of engineering which requires only intellectual work.  Practically all successful engineers are of the bony and muscular type or some modification of this type.  This is the type which naturally takes interest in construction, in machinery, and in material accomplishment and achievement.  Engineering practice usually requires painstaking accuracy and exactitude.  Indeed, this is perhaps more than any other one qualification fundamental for success in engineering.

THE PROFESSIONAL TYPE

This, then, is the composite photograph of the successful professional man:  He is more mental than physical; more scientific, philosophic, humanitarian, and idealistic than commercial; more social and friendly than exclusive and reserved; more ambitious for professional high standing or achievement than for wealth or power.  Unless the aspirant to professional honors has some or all of these qualifications in a considerable degree, he would better turn his attention to some other vocation where there is not so much competition.  Those who have some, but not all, of these qualities would do well in other vocations, such as literature, finance, commerce, or manufacture.  Many physicians become authors, inventors, or financiers; many lawyers become financiers or manufacturers; many engineers become good advertising men, manufacturers, or merchants.  All such would have done better to begin in the vocation to which they afterward turned.

A good rule for the young man or the young woman to follow is to make up his or her mind to enter some other vocation rather than a profession unless he or she is markedly well qualified to outdistance the crowd of mediocre competitors and make an unusual success.
