Success depends on how many experiments you can fit into 24 hours
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.
I've realized that most of my best ideas have followed a good night's sleep.
I find out what the world needs. Then I go ahead and try to invent it
I try not to invent things that people don't need.
You can't realize your dreams unless you have one to begin with.
