Thomas Edison

It is wonderful what strength of purpose and boldness and determination carry man through.

The only joy is in creation.

I am long on ideas, but short on time.

As a cure for worrying, work is better than whiskey.

I haven't failed. I've identified 10,000 ways that don't work.

I never perfected an invention that I did not think about in terms of the service it might give to others.

The mind can do anything.

Time is really the only capital that any human being has, and the only thing he can't afford to lose.

Results! Why, man, I have gotten a lot of results. I know several thousand things that won't work.

The first thing is to find out what the world needs, then to proceed with the invention.

There is no expedient to which a man will not resort to avoid the real labor of thinking.

I never perfected an invention that I did not think about in terms of the service it might give to others... I find out what the world needs, then I proceed to invent it.

The more a man knows, the more he forgives.

I don't care so much for the money as I do for the fun of the thing.

We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature's inexhaustible sources of energy—sun, wind and tide.

My main purpose in life is to make money so that I can afford to finance more inventions.

I don't think there's any substitute for a good, hard day's work.

I have friends in all walks of life, and I am not ashamed to say that I have learned something from them all.

The mind can be a powerful tool, but it can also be a dangerous one.

I never perfected an invention that I did not think in terms of the service it might give others.
