Read this excerpt from Henry Ford’s autobiography, My Life and Work. We were a prosperous company. We might easily have sat down and said: "Now we have arrived. Let us hold what we have got." Indeed, there was some disposition to take this stand. Some of the stockholders were seriously alarmed when our production reached one hundred cars a day. They wanted to do something to stop me from ruining the company, and when I replied to the effect that one hundred cars a day was only a trifle and that I hoped before long to make a thousand a day, they were inexpressibly shocked and I understand seriously contemplated court action. . . . The temptation to stop and hang on to what one has is quite natural. I can entirely sympathize with the desire to quit a life of activity and retire to a life of ease. I have never felt the urge myself but I can comprehend what it is – although I think that a man who retires ought entirely to get out of a business. There is a disposition to retire and retain control. It was, however, no part of my plan to do anything of that sort. I regarded our progress merely as an invitation to do more.
