I Think Work Is The World's Greatest

Success Is The Result Of Hard Work.

There Is No Substitute For Hard Work.

I Make More Mistakes Than Anyone Else I Know, And Sooner Or Later, I Patent Most Of Them.

I Am Much Less Interested In What Is Called God's Word Than In God's Deeds. All Bibles Are Man-made.

My Main Purpose In Life Is To Make Money So I Can Afford To Go On Creating More Inventions.
