There is great value in disaster. All our mistakes are burned up. Thank God we can start a new.

I will not say I failed 1000 times, I will say that I discovered there are 1000 ways that can cause failure

I am not overly impressed by the great names and reputations of those who might be trying to beat me to an invention. It's their 'ideas' that appeal to me. I am quite correctly described as 'more of a sponge than an inventor

I failed my way to success.

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

Until man duplicates a blade of grass, nature can laugh at his so called scientific knowledge.

I've realized that most of my best ideas have followed a good night's sleep.
