"The three great essentials to achieve anything worth while are, first, hard work; second, stick-to-itiveness; third, common sense. " 

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

"We often miss opportunity because it's dressed in overalls and looks like work" 

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

"Negative results are just what I want. They’re just as valuable to me as positive results. I can never find the thing that does the job best until I find the ones that don’t." 

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