Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.
~ Thomas A. Edison
The best thinking has been done in solitude. The worst has been done in turmoil.
To have a great idea, have a lot of them.
Great ideas originate in the muscles.
To my mind the old masters are not art their value is in their scarcity.
There's a way to do it better - find it.
One might think that the money value of an invention constitutes its reward to the man who loves his work. But... I continue to find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.
Genius is one percent inspiration and ninety-nine percent perspiration.
Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.
I find my greatest pleasure, and so my reward, in the work that precedes what the world calls success.
