“I have always kept,” continued Mr. Edison, “strictly within the lines of commercially useful inventions. I have never had any time to put on electrical wonders, valuable only as novelties to catch the popular fancy.”

“I LIKE IT—I HATE IT”

“What makes you work?” I asked with real curiosity. “What impels you to this constant, tireless struggle? You have shown that you care comparatively nothing for the money it makes you, and you have no particular enthusiasm for the attending fame. What is it?”

“I like it,” he answered, after a moment of puzzled expression. “I don’t know any other reason. Anything I have begun is always on my mind, and I am not easy while away from it, until it is finished; and then I hate it.”

“Hate it?” I said.

“Yes,” he affirmed, “when it is all done and is a success, I can’t bear the sight of it. I haven’t used a telephone in ten years, and I would go out of my way any day to miss an incandescent light.”[[5]]

[5]. “After I have completed an invention,” remarked Edison, upon another occasion, “I seem to lose interest in it. One might think that the money value of an invention constitutes its reward to the man who loves his work. But, speaking for myself, I can honestly say this is not so. Life was never more full of joy to me, than when, a poor boy, I began to think out improvements in telegraphy, and to experiment with the cheapest and crudest appliances. But now that I have all the appliances I need, and am my own master, I continue to find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.”

DOING ONE THING EIGHTEEN HOURS IS THE SECRET

“You lay down rather severe rules for one who wishes to succeed in life,” I ventured, “working eighteen hours a day.”

“Not at all,” he said. “You do something all day long, don’t you? Every one does. If you get up at seven o’clock and go to bed at eleven, you have put in sixteen good hours, and it is certain with most men, that they have been doing something all the time. They have been either walking, or reading, or writing, or thinking. The only trouble is that they do it about a great many things and I do it about one. If they took the time in question and applied it in one direction, to one object, they would succeed. Success is sure to follow such application. The trouble lies in the fact that people do not have an object—one thing to which they stick, letting all else go. Success is the product of the severest kind of mental and physical application.”
