“A man of sedentary occupation goes for a very long walk on Easter Monday, and in the evening is so exhausted that he can scarcely eat. He wakes up to the inefficiency of his body, caused by his neglect of it, and he is so shocked that he determines on remedial measures. Either he will walk to the office, or he will play golf, or he will execute the post-shaving exercises. But let the same man after a prolonged sedentary course of newspapers, magazines, and novels, take his mind out for a stiff climb among the rocks of a scientific, philosophic, or artistic subject. What will he do? Will he stay out all day, and return in the evening too tired even to read his paper? Not he. It is ten to one that, finding himself puffing for breath after a quarter of an hour, he won't even persist till he gets his second wind, but will come back at once. Will he remark with genuine concern that his mind is sadly out of condition and that he really must do something to get it into order? Not he. It is a hundred to one that he will tranquilly accept the status quo, without shame and without very poignant regret. Do I make my meaning clear?” Mental efficiency is an important and ACQUIRED state of mind. It is a strength that must be and can only be developed from within. Mental Efficiency and Other Hints to Men and Women is nothing less than time honored “standard procedure” necessary to develop that strength and begin to make true and lasting positive changes in your life.
