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.

I owe my success to the fact that I never had a clock in my workroom. Seventy-five of us worked twenty hours every day and slept only four hours - and thrived on it.

When we learn how to store electricity, we will cease being apes ourselves; until then we are tailless orangutans. You see, we should utilize natural forces and thus get all of our power. Sunshine is a form of energy, and the winds and the tides are manifestations of energy. Do we use them? Oh, no! We burn up wood and coal, as renters burn up the front fence for fuel. We live like squatters, not as if we owned the property.

People are not remembered by how few times they fail, but by how often they succeed. Every wrong step is another step forward

After we had conducted thousands of experiments on a certain project without solving the problem, one of my associates, after we had conducted the crowning experiment and it had proved a failure, expressed discouragement and disgust over our having failed to find out anything. I cheerily assured him that we had learned something. For we had learned for a certainty that the thing couldnt be done that way, and that we would have to try some other way.

Five percent of the people think; ten percent of the people think they think; and the other eighty-five percent would rather die than think.

I am long on ideas, but short on time. I expect to live to be only about a hundred.
