If I could solve all the problems myself, I would.

We are striking it big in the electric light, better than my vivid imagination first conceived. Where this thing is going to stop Lord only knows.

I never did anything worth doing entirely by accident. . . Almost none of my inventions came about totally by accident. They were achieved by having trained myself to endure and tolerate hard work.

Of the 200 light bulbs that didn't work, every failure told me something that I was able to incorporate into the next attempt.

I find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.

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.".

As a cure for worrying, work is far better than whiskey. I always found that, if I began to worry, the best thing I could do was focus upon doing something useful and then work very hard at it. Soon, I would forget what was troubling me.
