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

Great ideas originate in the muscles.

I remember that I was never able to get along at school. I was at the foot of the class.

I have not failed 700 times. I have not failed once. I have succeeded in proving that those 700 ways will not work. When I have eliminated the ways that will not work, I will find the way that will work.

From his neck down a man is worth a couple of dollars a day, from his neck up he is worth anything that his brain can produce.

I start where the last man left off. What the mind of man can conceive and believe, the mind of a man can achieve.
