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

One might think that the money value of an invention constitutes its reward to the man who loves his work. But... I continue to find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.

I owe my success to the fact that I never had a clock in my workroom.

I never did a day's work in my life. It was all fun.

I find out what the world needs. Then I go ahead and try to invent it

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.

There is a better way for everything. Find it.

When you have exhausted all possibilities, remember this - you haven't.

Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.
