I never pick up an item without thinking of how I might improve it. I never perfected an invention that I did not think about in terms of the service it might give others. I want to save and advance human life, not destroy it. I am proud of the fact that I never invented weapons to kill. The dove is my emblem.

I am 67, but I'm not too old to make a fresh start.

Never be discouraged, because every wrong turn attempt, when left behind you, is another step forward taking you closer to your goals.

Mr. Edison worked endlessly on a problem, using the method of elimination. If a person asked him 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.".

The thing I lose patience with the most is the clock. Its hands move too fast
