There Is No Subsitute For Hard Work.

I Have Not Failed 10,000 Times. I Have Succeeded In Proving That Those 10,000 Ways Will Not Work.

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

I Never Did Anything Worth Doing By Accident, Nor Did Any Of My Inventions Come Indirectly Through Accident, Except The Phonograph. No, When I Have, Fully Decided That A Result Is Worth Getting, I Go About It, And Make Trial After Trial, Until It Comes.

I Owe My Success To The Fact That I Never Had A Clock In My Workroom.

The Inventor Can't Do It All, You've Got To Change People. We Have An Enormous Capacity To Invent Super-machinery. But Our Desire To Install The Device Is Weak. Human Inertia Is The Problem, Not Invention. Something In Man Makes Him Resist Change.
