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

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!

There is much more opportunity than there are people to see it.

Negative results are just what I want. They’re just as valuable to me as positive results. I can never find the thing that does the job best until I find the ones that don’t.

My mother was the making of me.

Most of the exercise I get is from standing and walking around laboratory tables all day. I derive more benefit and entertainment from this than some of my friends and competitors get from playing games like golf.

I believe in the existence of a Supreme Intelligence pervading the Universe.
