A valid observation from one of America's greatest inventors!

Interestingly, Dr Maxwell Maltz mentioned quite a lot about Thomas Edison in his Psycho-Cybernetics classic:

• his well-known cap naps, when stymied by a problem (that's probably how the idiom "sleep on it" came about!);
• Edison approached his projects by employing a process of elimination. He was convinced that experimentation was a process of eliminating what doesn't work. He always did well to keep accurate records of every experiment;
• not discouraged by numerous failed attempts; when asked if he were discouraged because so many attempts proved unavailing, he would say, "No, I am not discouraged, because every wrong attempt discarded is another step forward.".
• his loss of a lab worth millions in a fire with no insurance didn't deter him from his seemingly aggressive goal-oriented atttitude: When someone asked: "What in the world will you do?" Edison responded: "We will start rebuilding tomorrow!" That's also the essence of stick-to-itiveness!
