This book is a collection of 92 fundamental quotes and aphorisms of Thomas Edison: I start where the last man left off. Everyone steals in commerce and industry. I've stolen a lot, myself. But I know how to steal! They don't know how to steal! All bibles are man-made. Great ideas originate in the muscles. I am proud of the fact that I never invented weapons to kill. Show me a thoroughly satisfied man and I will show you a failure. Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.
