I have not failed. I have successfully discovered 1200 ideas that don't work.

I never did anything by accident, nor did any of my inventions come by accident; they came by work.

Success is based on imagination plus ambition and the will to work.

My principal business is giving commercial value to the brilliant - but misdirected - ideas of others.

Interest is the invention of Satan.

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!
