Note 5 — XIV

“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.”
