"I find my greatest pleasure, and so my reward, in the work that precedes what the world calls success."

"I have not failed. I've just found 10,000 ways that won't work."

"I never did a day's work in my life. It was all fun."

"I never did anything by accident, nor did any of my inventions come by accident; they came by work."

"Many of life's failures are people who did not realize how close they were to success when they gave up."

"One might think that the money value of an invention constitutes its reward to the man who loves his work. But... I continue to find my greatest pleasure, and so my reward, in the work that precedes what the world calls success."

"Opportunity is missed by most people because it is dressed in overalls and looks like work."

"Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time."

"Religion is all bunk."

"Restlessness is discontent and discontent is the first necessity of progress. Show me a thoroughly satisfied man and I will show you a failure."

"Results! Why, man, I have gotten a lot of results. I know several thousand things that won't work."

"Show me a thoroughly satisfied man and I will show you a failure."

"The best thinking has been done in solitude. The worst has been done in turmoil."

"The doctor of the future will give no medicine but will instruct his patient in the care of the human frame, in diet, and the cause and prevention of disease."

"The reason a lot of people do not recognize opportunity is because it usually goes around wearing overalls looking like hard work."

"There is no substitute for hard work."

"There will one day spring from the brain of science a machine or force so fearful in its potentialities, so absolutely terrifying, that even man, the fighter, who will dare torture and death in order to inflict torture and death, will be appalled, and so abandon war forever."

"There's a way to do it better - find it."

"To my mind the old masters are not art; their value is in their scarcity."

"What you are will show in what you do."
