You are a busy person, so am I. Busy persons are the ones who do things. The architect is a busy man, but he has learned that the time spent in preparing his plans is the most valuable employment of his time. The plans enable him to do his work systematically and lay down rules and methods to get the highest efficiency and accomplishment from those who do the work of erecting the building. If the architect would order lumber, stone and hardware, without system, and start to erect the building without carefully prepared plans, the building would lack symmetry and strength, and it would be most expensive. The planning time therefor was time well spent. Few persons have the ability to plan and conserve their talents so as to produce the highest efficiency. Men rush along thinking their busyness means business. Really it means double energy and extra moves to produce a given effect. The elimination of unnecessary moves means operating along lines of least resistance, and any plan or method that will help to do away with unnecessary moves and make the necessary moves more potential will be received with welcome, I am sure. With the object of conserving energy and strengthening your force, this book is written. It shall not be a book of ultimate definiteness or a book of exact science. There is no definite or exact rule that will apply, without exceptions, to any science except mathematics. But we shall learn many helpful truths, nevertheless, and if I err or disagree with your conclusions, just eliminate those lines and take the helps you find. In my previous book, "Pep," I particularly emphasized the importance of taking a few minutes each evening and using the time for sizing up things, by inventory, analysis, speculation, comparison and hypothesis. I have received many comments about that particular suggestion. I find that many of the great captains of industry who are accomplishing things worth while, have learned the value of this daily habit. Mr. E. C. Simmons, the president of the Simmons Hardware Company, has for about fifty years followed this daily sizing up plan. He takes fifteen to twenty minutes each evening in seclusion, with closed eyes, and finds the weaknesses of his plans, formulates new plans, and generates new ideas for the morrow. He says this habit is one of the greatest contributing factors to his success and to the building up of the largest hardware business the world has ever known. I want to help YOU to form the habit of rounding up each day's activities in the quiet, relaxed, uncolored, unprejudiced secluded environment of your home. Each evening we will together size up things--a sort of daily round-up.
