Vision without execution is delusion.
I never did anything by accident, nor did any of my inventions come by accident; they came by work.
The first requisite for success is to develop the ability to focus.
The trouble with most people is that they quit before they start.
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….
I owe my success to the fact that I never had a clock in my workroom.
