Restlessness is discontent and discontent is the first necessity of progress
Why, man, I have gotten a lot of results.
I know several thousand things that won't work.
The best thinking has been done in solitude. The worst has been done in turmoil.
The body is a community made up of its innumerable cells or inhabitants.
I never perfected an invention that I did not think about in terms of the service it might give others... I find out what the world needs, then I proceed to invent.
And because I readily absorb ideas from every source - frequently starting where the last person left off - I never pick up an item without thinking of how I might improve it.
A good idea is never lost. Even though its originator or possessor may die, it will someday be reborn in the mind of another.
The chief function of the body is to carry the brain around.
My main purpose in life is to make money so I can afford to go on creating more inventions. Most nerve strain of our modern life, I fancy, comes to us through our ears.
When a person hears the name Thomas Edison they think of a smart, well-educated man who invented things for money and himself. Thatís what I thought before, so I decided to see if I was right.
If the Nation can issue a dollar bond it can issue a dollar bill. The element that makes the bond good makes the bill good also.
The difference between the bond and the bill is that the bond lets the money broker collect twice the amount of the bond and an additional 20%. This is the terrible thing about interest.
Whereas the currency, the honest sort provided by the Constitution pays nobody but those who contribute in some useful way.
