Genius is 1 percent inspiration, 99 percent perspiration.

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 never did a day's work in my life, it was all fun.

Be courageous. I have seen many depressions in business. Always America has emerged from these stronger and more prosperous. Be brave as your fathers before you. Have faith! Go forward!

To have a great idea, have a lot of them.

I am long on ideas, but short on time. I expect to live to be only about a hundred.

The First 40 hours of work per week are for survival. Everything after that is for success.
