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

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

I would construct and work along various lines until I found them untenable. When one theory was discarded, I developed another at once. I realized very early that this was the only possible way for me to work out all the problems.

You can't realize your dreams unless you have one to begin with.

Invention is 1% inspiration and 99% perspiration

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

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.

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

A good idea is never lost. Even though its originator or possessor may die, it will someday be reborn in the mind of another.

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 sleep per night.

I have not failed. I have successfully discovered 1200 ideas that don't work.

And where do His mercy, kindness, and love for that fish come in? No; nature made us - nature did it all - not the gods of the religions.

I believe that the motion picture is destined to revolutionize our educational system and that in a few years it will supplant largely, if not entirely, the use of textbooks.

When I have eliminated the ways that will not work, I will find the way that will work.

Nobody knows whether our personalities pass on to another existence or sphere, but if we can evolve an instrument so delicate to be manipulated by our personality as it survives in the next life such an instrument ought to record something.

I owe my success to the fact that I never had a clock in my workroom. Seventy-five of us worked twenty hours every day and slept only four hours - and thrived on it.

Never go to sleep_x000D_ without a request to your subconscious.

Of all my inventions, I liked the phonograph best

A genius is a talented person who does his homework.

To get a great idea, come up with lots of them.
