Thomas A. Edison

I have never seen the slightest scientific proof of the religious idea of heaven and hell, of future life for individuals, or of a personal God.

Many of life's failures are those who didn't know how close they were to success when they gave up.

If I find 10,000 ways something won't work, I haven't failed. I am not discouraged, because every wrong attempt discarded is another step forward.

The doctor of the future will give no medicine, but will educate his patients in the care of the human frame, in diet, and in the cause and prevention of disease.

A genius is just a talented person who does his homework.

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

Remember, nothing that's good works by itself, just to please you. You have to make the damn thing work.

Faith, as well intentioned as it may be, must be built on facts, not fiction--faith in fiction is a damnable false hope.

The doctor of the future will give no medicine, but will interest her or his patients in the care of the human frame, in a proper diet, and in the cause and prevention of disease.

I never did anything worth doing by accident, nor did any of my inventions come by accident

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

Opportunity is missed by most people because it is dressed in overalls and looks like work.

Hell, there are no rules here-- we're trying to accomplish something.

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

Genius is one percent inspiration, ninety-nine percent perspiration.

Hell, there are no rules here--we're trying to accomplish something.

Everything comes to him who hustles while he waits.

All Bibles are man-made.

Genius is one per cent inspiration, ninety-nine per cent perspiration.

Just because something doesn't do what you planned it to do doesn't mean it's useless.

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

To invent, you need a good imagination and a pile of junk.

We don't know a millionth of one percent about anything.

If we all did the things we are capable of doing, we would literally astound ourselves.

I have not failed. I've just found 10,000 ways that won't work.

Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.

Many of life's failures are people who did not realize how close they were to success when they gave up.
