¶ Science has taken the trouble to investigate and today we know not only where grandmother got it but what she did with it. She got it along with her size, shape and structure--in other words, from her type--and she did just what you and everybody else does with his type-characteristics. She acted in accordance with her type just as a canary sings like a canary instead of talking like a parrot, and just as a rose gives off rose perfume instead of violet. This law holds throughout every species and explains man--who likes to think himself a deep mystery--as it explains every other creature. The Hold of Habit ¶ Look around you in shop, office, field or home and you will find that the quick, alert, impulsive man is acting quickly, alertly and impulsively most of the time. Nothing less than a calamity slows him down and then only temporarily; while the slow, patient, mild and passive individual is acting slowly, patiently, mildly and passively in spite of all goads. Some overwhelming passion or crisis may speed him up momentarily but as soon as it fades he reverts to his old slow habits. Significance of Fat, Bone and Muscle ¶ Human Analysis is the new science which shows you how to recognize the slow man, the quick man, the stubborn man, the yielding man, the leader, the learner, and all other basic kinds of men on sight from the shape, size and structure of their bodies. 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.
