Certain bodily shapes indicate predispositions to fatness, leanness, boniness, muscularity and nervousness, and this predisposition is so much a part of the warp and woof of the individual that he can not disguise it. The urge given him by this inborn mechanism is so strong as to be practically irresistible. Every experience of his life calls forth some kind of reaction and invariably the reaction will be similar, in every vital respect, to the reactions of other people who have bodies of the same general size, shape and structure as his own.
Succeed at What We Like
¶ No person achieves success or happiness when compelled to do what he naturally dislikes to do. Since these likes and dislikes stay with him to the grave, one of the biggest modern problems is that of helping men and women to discover and to capitalize their inborn traits.
Enthusiasm and Self-Expression
¶ Every individual does best those things which permit him to act in accordance with his natural bents. This explains why we like best those things we do best. It takes real enthusiasm to make a success of any undertaking for nothing less than enthusiasm can turn on a full current.
We struggle from the cradle to the grave for self-expression and everything that pushes us in a direction opposed to our natural tendencies is done half-heartedly, inefficiently and disgruntledly. These are the steps that lead straight to failure. Yet failure can be avoided and success approximated by every normal person if he will take the same precaution with his own machinery that he takes with his automobile.
Learn to Drive Your Car
¶ If you were presented with a car by your ancestors—which is precisely what happened to you at birth—you would not let an hour go by without finding out what make or type of car it was. Before a week elapsed you would have taken the time, labor and interest to learn how to run it,—not merely any old way, but the best way for that particular make of car.
Five Makes of Human Cars
¶ There are five makes or types of human cars, differing as definitely in size, shape and structure as Fords differ from Pierce-Arrows. Each human type differs as widely in its capacities, possibilities and aptitudes as a Ford differs from a Pierce-Arrow. Like the Ford or Pierce the externals indicate these functional differences with unfailing accuracy. Furthermore just as a Ford never changes into a Pierce nor a Pierce into a Ford, a human being never changes his type. He may modify it, train it, polish it or control it somewhat, but he will never change it.
