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.

The three great essentials to achieve anything worth while are: Hard work, Stick-to-itiveness, and Common sense.

The stomach is the only part of man which can be fully satisfied. The yearning of man's brain for new knowledge and experience and for more pleasant and comfortable surroundings never can be completely met. It is an appetite which cannot be appeased.

What you are will show in what you do.

My main purpose in life is to make enough money to create ever more inventions…. The dove is my emblem…. I want to save and advance human life, not destroy it…. I am proud of the fact that I have never invented weapons to kill….

The secret of success is focus of purpose.

Invention is 10% inspiration and 90% perspiration.
