“Thinking is the hardest work there is, which is probably the reason so few engage in it.”

“That the Devil finds work for idle hands to do is probably true. But there is a profound difference between leisure and idleness.”

“I invented nothing new. I simply assembled the discoveries of other men behind whom were centuries of work. Had I worked fifty or ten or even five years before, I would have failed. So it is with every new thing. Progress happens when all the factors that make for it are ready, and then it is inevitable. To teach that a comparatively few men are responsible for the greatest forward steps of mankind is the worst sort of nonsense.”

“None of our men are 'experts.' We have most unfortunately found it necessary to get rid of a man as soon as he thinks himself an expert because no one ever considers himself expert if he really knows his job. A man who knows a job sees so much more to be done than he has done, that he is always pressing forward and never gives up an instant of thought to how good and how efficient he is. Thinking always ahead, thinking always of trying to do more, brings a state of mind in which nothing is impossible. The moment one gets into the 'expert' state of mind a great number of things become impossible.”

“Where people work longest and with least leisure, they buy the fewest goods. No towns were so poor as those of England where the people, from children up, worked fifteen and sixteen hours a day. They were poor because these overworked people soon wore out -- they became less and less valuable as workers. Therefore, they earned less and less and could buy less and less.”

“To teach that a comparatively few men are responsible for the greatest forward steps of mankind is the worst sort of nonsense.”

“The way to learn to do things is to do things. The way to learn a trade is to work at it. Success teaches how to succeed. Begin with the determination to succeed, and the work is half done already.”
