Negative results are just what I want. They’re just as valuable to me as positive results. I can never find the thing that does the job best until I find the ones that don’t.

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

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

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

Genius is one per cent inspiration and ninety-nine per cent perspiration. A genius'is often merely a talented person who has done all of his or her homework. Opportunity is missed by most people because it is dressed in overalls and looks like work.

The first requisite for success is to develop the ability to focus and apply your mental and physical energies toward solving the problems at hand - without growing weary. Because such thinking can often be difficult, there seems to be no limit to which most people will go to avoid the effort and labor that is associated with it...

I never did anything worth doing entirely by accident.... Almost none of my inventions were derived in that manner. They were achieved by having trained myself to be analytical and to endure and tolerate hard work

Inspiration can often be found in a pile of junk. Sometimes, you can put it together with a good imagination and invent something.

Personally, I enjoy working about 18 hours a day. Besides the short catnaps I take each day, I average about four to five hours of deep sleep per night.

Most of the exercise I get is from standing and walking all day from one laboratory table to another. I derive more enjoyment, benefit and entertainment from this than some of my friends and competitors get from playing games like golf.

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

Our schools are not teaching students to think. It is astonishing how many young people have difficulty in putting their brains definitely and systematically to work....

The three things that are most essential to achievement are: common sense, hard work and stick-to-it-iv-ness.....

I have far more respect for the person with a single idea who gets there than for the person with a thousand ideas, who actually does nothing...

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

Pretty much everything will come to him who hustles while he waits. I believe that restlessness is discontent, and discontent is merely the first necessity of progress. Show me a thoroughly satisfied man and I will show you a failure.

Unfortunately, there seems to be far more opportunity out there than ability.... We should remember that good fortune often happens when opportunity meets up with good preparation.

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

Results? Why, man, I have gotten lots of results! If I find 10,000 ways something won't work, I haven't failed. I am not discouraged, because every wrong attempt discarded is often a step forward....

Surprises and reverses can serve as an incentive for great accomplishment. There are no rules here, we're just trying to accomplish something....

As a cure for worrying, work is far better than liquor. Personally, 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.

Barring serious illlness or accidents, if you are not preoccupied with worry and you work hard, you can look forward to a reasonably lengthy existence.... Its usually not the hard work that kills us, its worrying that kills.

The only time I really become discouraged is when I think of all the things I would like to do and the little time I have in which to do them.

The thing I lose patience with the most is the clock. Its hands move too fast.

Time is really the only capital that any human being has and the thing that he can least afford to waste or lose...

From his neck down a man is worth a couple of dollars a day, from his neck up he is worth anything that his brain can produce.

The doctor of the future will prescribe virtually no medicine, but will interest his patients in the care of the human body, in diet, and in the cause and prevention of disease.

Whatever the mind of man creates, should be controlled by man's character.

I love great music and art, but quite frankly I think 'cubist' paintings and songs are hideous.

Someday, man will harness the rise and fall of the tides, imprison the power of the sun and fully release electromagnetic and atomic power.

I am both pleased but astonished by the fact that mankind has not yet begun to use all the means and devices that are available for destruction. I hope that such weapons are never manufactured in quantity.

The United States, and other advanced nations, will someday be able to produce instruments of death so terrible the world will be in abject terror of itself and its ability to end civilization.... If such war-making weapons are developed, they should - but only for purposes of peaceful experimentation....

The dove is my emblem.... I want to save and advance human life, not destroy it.... I am proud of the fact that I never invented weapons to kill...

To me, the idea and expectation that the day is slowly and surely coming when we will be able to honestly say we are our brother's keeper - and not his oppressor - is very beautiful .

Until man duplicates a blade of grass, nature can laugh at his so-called scientific knowledge....

Its obvious that we don't really know one millionth of one percent about anything.

I believe that the science of chemistry alone almost proves the existence of an intelligent creator. We have merely scratched the surface of the store of knowledge which will eventually come to us. I believe that we are always on the verge of many vast discoveries, which - whsch will be so important they will upset the present trend of human thought and start us along completely new lines ....

Be courageous! Whatever setbacks America has encountered, it has always emerged as a stronger and more prosperous nation.... Be brave as your fathers before you. Have faith and go forward!

If parents can pass enthusiasm along to their children, they will leave them an estate of incalculable value...

The memory of my mother will always be a blessing to me....

Life's two most soothing things are a child's goodnight and sweet music.

Even though I am nearly deaf, I seem to be gifted with some kind of an inner hearing which enables me to detect sounds and noises that normal listeners do not perceive.

Of all my inventions, I liked the phonograph best...."
